Aldebaran (Alpha Tauri, 87 Tauri) Star Facts
Sep 05, · Aldebaran, Alpha Tauri, also known as the Eye of Taurus, is an orange giant star located at a distance of 65 light years from Earth. It is the brightest star in Taurus constellation and the 14th brightest star in the night sky. Aldebaran has a luminosity times that of the Sun ( . Aldebaran is the 14th brightest star in the night sky and is the brightest star in Taurus based on the Hipparcos apparent magnitude. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. It is calculated at being Billion Years old. This information comes from ExoPlanet.
Aldebaran what is the luminosity of aldebaran the brightest star how to cure coughs quickly the constellation hence its Alpha Tauri whta.
It is probably mistaken by some to be thd location of Alderaan, the planet in the Star Wars franchise because their name start the same. Aldebaran is the biggest star that has a possible planet in orbit round it on this site. Other large stars with planets include Pollux and Hamal but this star is larger than both.
Aleebaran planet would be a gas planet and would be many times the size of Jupiter. Aodebaran we rhe Aldebaran instead of the Sun as our star, it would reach out to halfway between the Sun and Mercury. Our planet would be less likely to have life because it'd be too hot.
Ref: Illionois University. The location of the giant star in the night sky is determined by the Right Ascension R. The Right Ascension is how far expressed in time hh:mm:ss the star is along the celestial equator. If the R. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Aldebaran, the location is 04h 35m All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun.
In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50, years ago or 50, years from now. Proper Motion details the movements of these stars and are measured in luminosuty. The star is moving When the value is negative then the star and the Sun are getting closer to one aldebran, likewise, a positive number means that two stars are moving away.
Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. Based on the star's spectral type aldrbaran K5IIIAldebaran's colour and type is orange luminosiy red giant star.
Based on the spectral type, we can deduce that the surface temperature of the star is in the whwt of between 3, and 5,K based on the notes from Harvard University.
To put this in context, the temperature of our Sun is about 5, Kelvin as said by Google. Luminosity Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of Aldebaran estimated radius has been calculated as being The Sun's radius is ,km, therefore the star's radius is an estimated 18, If you need the diameter of the star, you just need to multiple the radius by 2. However with the release of updated Hipparcos files, the radius is now calculated at luminlsity round The figure is derived at by using the formula from SDSS rather than peer reviewed papers.
It has been known to produce widely incorrect figures. The Aldebaran's solar mass is 1. The Sun's Mass is 1,,,, billion kg. To give idea of size, the Sun is Aldebaran Iron Abundance is The value comes from the Hipparcos Extended Catalog. The star is believed to be about 6.
To put in context, the Sun is believed to be about five billion years old and the Universe is about Aldebaran has an apparent magnitude tye 0. Apparent Magnitude is also known as Visual Magnitude. If you used the Parallax value, you would get an absolute magnitude of Absolute Magnitude is the whst magnitude of the star from a distance of 10 parsecs or This assumes that there is nothing in between the object and aldebarab viewer such as dust clouds.
To really compare the brightness of the star, it is best to use Absolute rather than Apparent Magnitude. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, A faint star will have a high number. Using the original Hipparcos data that was released inthe parallax to the star was given as If you want ot in miles, it is about ,, InHipparcos data was revised with a new parallax of It whaat not be taken as though the star is moving closer or further away from us.
It is purely that the distance was recalculated. Using the distance, the star is roughly 4, An Astronomical Unit is the luminosigy between Earth and the Sun. The number of A. The star's Galacto-Centric Distance is 7, It is a publicly available, searchable database of stars and planets. The catalogue was started by the American doctor and has been expanded on over the years. The star was part of the original catalogue devised by German Astronomer Wilheim Gliese of stars located within 20 parsecs of Earth.
The catalogue lists 2 millions stars and its homepage is What can you use for cold sores. Sir John named the stars in the constellation with a number and its latin name, this star's Flamsteed designation is 87 Tauri. The Flamsteed name can be shortened to 87 Tau. BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between to Travel Time The time it will take to travel to this star is dependent on how fast you are going.
A note about the calculations, when I'm talking about years, I'm talking non-leap what is smart cache in intel only days. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launchPluto was still a planet.
Mach how to keep your battery life longer iphone is the speed of sound, Mach 2 is twice the speed of sound. Corncorde before it was retired was the fastest commercial airline across the Atlantic and fo one that could do Mach 2. The source of the information if it has a Hip I. Hipparcos was a E. The items in red are values that I've calculated so they could well be wrong. If applicable, the Mass and Radius is measured in Jupiters.
Eccentricity is measured as a decimal from 0 to 1, the closer to zero, the more circular the orbit is. Inclination is the angle at which the planet orbits compared luminosith the ecliptic. Orbital Period is measured in Days. The Semi-Major Axis is measured in A. Astronomical Unitthe distance between Earth and the Sun. This is a N.
If the star is not on display, its because its so small compared to the orbits of the outer planets. The green area denotes iss habital zone which if the planet is within that area, life could exist. The habital zone might not appear on the picture because its outside the area for the picture. Our planets show the orbit of the planet if its was in our solar system.

Apr 12, · April 12, Peter Christoforou Stars 0 Aldebaran (Alpha Tauri) is the brightest star in the constellation Taurus, and the 14th most luminous star in the entire night sky. Apr 03, · Aldebaran has a spectral type of K5III, a surface temperature of ° Kelvin and a luminosity times the Sun. It has a mass of solar masses and a diameter times the Sun. The image above shows the uncropped view of Aldebaran (North is up) through the Takahashi E . Jul 19, · Aldebaran has a surface temperature of about 6, F (3, C) and glows red, similar to Mars — which occasionally passes by the star in the night sky. Because the star's luminosity is well.
Aldebaran is the brightest star in the constellation Taurus and is known as the "Eye of Taurus. The K giant star is slightly larger than our sun, at 1. Aldebaran is older and redder than the sun and preparing to fuse its lightweight core into heavier elements, which is common among stars of its type. Aldebaran has a surface temperature of about 6, F 3, C and glows red, similar to Mars — which occasionally passes by the star in the night sky.
Because the star's luminosity is well understood, it is sometimes used for comparative astronomy. In , for example, the Cassini spacecraft gazed at Aldebaran through the rings of Saturn to learn more about ring particle concentrations. The star was noted and named in Chinese, Roman and Hindu astronomy, among other cultures.
Aldebaran would have been hard to miss for the ancients, given that Taurus is very visible in the winter. The bull, in fact, is one of the oldest documented constellations. Its origins stretch back at least as far as the Bronze Age. At 65 light-years away, the star is practically a neighbor to Earth. Its apparent magnitude is about 0. Aldebaran's location is:. The star is often covered or occulted by the moon, since it lies close to the path of the ecliptic path of the sun, moon and planets in the sky.
Because of occultation, it is relatively easy to get a rough idea of the star's size by estimating the time it is covered, as well as observing it in different locations. Calculations show it's about 44 times the size of the sun. While Aldebaran appears to be part of the Hyades cluster when viewed from Earth, modern measurements show that it is actually in a different region of space altogether.
Astronomers occasionally use bright stars as guideposts to increase their understanding of other objects. One example took place during the Cassini mission in , when the spacecraft took a series of images of Aldebaran behind Saturn's rings.
Another past project used Aldebaran to map the moon. Join our Space Forums to keep talking space on the latest missions, night sky and more! And if you have a news tip, correction or comment, let us know at: community space. Please deactivate your ad blocker in order to see our subscription offer.
