Trappist-1 is a star that can be located in the constellation of Aquarius. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it. Trappist-1 has at least 7 Extrasolar Planets believed to be in orbit around the star.
Trappist-1 is the alternate, more familiar name to its real name. The real name is 2MASS J23062928-0502285. Its a small insignificant star in the cosmos, one you won`t be able to see if you look up at the sky. It made the news in 2017 as it had the greatest number of exo-planets in orbit round any star, seven. No other system matches it yet.
The star is a small star compared to our Sun. The years on a planet are quick, you`ll "age" far far quicker than you would here. A year is a matter of days with the sixth planet orbit its star in less than a week. Some of the planets are within the goldilocks zone which could herald possible life.
Such was N.A.S.A.`s excitement of the discovery that they have a dedicated website Trappist-1 on it. The reason for studying small stars is that they planets have a more noticable pull on the star compared to giant star and therefore easier to detect. Its not to say that giant stars don`t have planets orbiting them, they do, take for instance the star Aldebaran, it has a planet orbiting it.

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 Trappist-1, the location is 23h 06m 29.28 and -05 ° 02` 28.5 .
