Assignment #2
The celestial object that I am chosing to do is called Kepler-21b. Kepler-21b is a planet that is interesting because it is near or almost the same size as the Earth. Kepler-21b has a sun that is just a bit bigger than ours and is only 6 million kilometers(3.7 million miles) away from it. With them being that close to each other, Kepler-21b is a scorching 2960 degrees fahrenheit. While its mass is about 10 times the size of our planet, its radius is only 1.6 times the size of Earth's. It was discovered today (Wednesday 12-1-11) by the National Optical Observatory. Kelper-21b is also only about 352 light years away from Earth. I found this was very interesting because we usually find planets that are much bigger, but now there's a planet that is almost the same size as us. http://www.huffingtonpost.com/2011/11/30/kepler-21b-new-planet-discovered_n_1121938.html#undefined
