In this topic I am going to babble with regards to the Red Dwarf Star Gliese 876, which is host to 3 exo- planets. Since Gliese 876 is a red dwarf star, that means that it is a somewhat cool for a star, burning at in regards to 3500K, and it is guessed to have only 32% of the mass our sun has. Since it is one of the tinier stars out there Gliese 876 can not be seen with the naked eye, you would need the aid of a telescope to view it. Hovering around in the constellation of Aquarius, Gliese 876 is in regards to 15 light years (or with regards to 4 and a half parsecs) away from our sun. We would’ve never thought that such a tiny star would harness habitable extrasolar-planets when it comes to fifteen years ago. In 1998 two exo-planet teams, one which was led by the famous exoplanet hunter Geoffrey Marcy, had found that there is a extrasolar-planet orbiting around Gliese 876. The planet was named Gliese 876b, and it was came upon by measuring the radial velocity of the star, as the planets strong gravity would pull on it is parent star causing it to wobble. Gliese 876 is guessed to have 2 times the mass of Jupiter and orbits it is parent star closer then Mercury does to our Sun, taking it with regards to 61 days to finish a full orbit. The next extrasolar planet that was found orbiting around Gliese 876 was came across just 3 years later in 2001. Gliese 876C was found to be orbiting Gliese even closer then Gliese 876B, taking it with regards to 30 days to finish a full orbit around it is parent star. This must cause a big gravitational battle when the the giant planets align up next to each other. Gliese 876C has a little more than half the mass of Jupiter. In 2005 a third extrasolar planet was encountered orbiting the red dwarf Gliese, named Gliese 876 d. Gliese 876 d is just hardly inside of what we call a stars habitable zone, we believe, and it has with regards to 6-7 times the mass of Earth, we think this might be a terrestrial planet. It takes Gliese 876 d regarding two days to finish a full orbit it is parent star. The sunrise on Gliese 876 must be lethal giving careful consideration to how close it is orbit is to it is star. So the two gas giants orbit the red dwarf in the so called habitable zone, because these are gas giants it is very improbable for them to harbor life. But what regarding the big moons of Gliese B and C ?(if there are any) There could be a moon orbiting Gliese b that could be beauteous close to the size of Earth. If all the conditions were right, where it’s just cool sufficient to have water, life could very well be possible. We might even find galore more extrasolar planets orbiting Gliese 876 in the future. Time and better looking at instruments will only tell if there is a extrasolar planet preserving life in the Gliese 876 solar system. |
