Teegarden`s Star is a red main sequence dwarf star that can be located in the constellation of Aries. The description is based on the spectral class.
eegarden`s star is one of the few stars that are named after an actual person. The person who discovered the Brown dwarf star is Bronnard Teegarden who discovered it in 2003 whilst working for national aeronautics and space administration (n.a.s.a.). He was the team leader of the group that found it and so it was named after him. It is a faint brown Dwarf Star which goes explains why it took so long in discovering it. It is one of the closest stars to our own the solar system and is the first Brown Dwarf that was discovered within 20 light years of us.
The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For Teegarden`s Star, the location is 2h 53m 0.85 and +16 ° 52` 53.3 .
Teegarden`s Star has a spectral type of M6.5 V. This means the star is a red main sequence dwarf star.
Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
