Gliese 581 c (Jot Singh)


 * Date of discovery**: April 4th 2007


 * Size**: 0.31 M meaning 6.166427 to the power of 29


 * Radius** : 0.29 R meaning 11 million km


 * Temperature** : 3480 + 48 K meaning its around


 * Atmosphere**: very earth like solid, dense carbon dioxide


 * Resources**: unable to find because it 20 light years away, but it is predicted to have similar elements as earth


 * Facts**: if we were to move to this planet we could create almost exact lifestyle in this planet because there is a possibility of finding water. It has much more gravity then earth. 13 earth days are 1 year of this planet


 * What we don’t know:** the life can be similar to earth because its frozen liquid and we don’t know if the temperature would change soon.

PSR B1620-26 b




 * Date of discovery**: May 30th 1993


 * Mass:** 0.34 means 6.763178 to the power of 29


 * Radius** : no exact number, but is more than double of Jupiter the size of Saturn (pretty big)


 * Temperature** : high enough to be visible in x-ray from earth


 * Atmosphere**: no data


 * Resources**: no data


 * Facts**: oldest planet in the extra solar planets, biggest planet, 12,400 light years away from earth


 * What we don’t know:** the atmosphere and resources that would be unable to find since its really far.

‪ Mu Arae c


 * Date of discovery**: August 25th2004


 * Mass:** 0.01M means 1.98917 to the power of 28


 * Radius**: 0.011 R means 7650500 km


 * Temperature** : 40,000 degrees


 * Atmosphere**: a gas planet which can go up to 900 K, rocky outside as well


 * Resources**: gas similar to Neptune, so like hydrogen helium methane but no living conditions, metals(not particular because its far)


 * Facts**: one revolution in 9.6 days


 * What we don’t know:** as most extra solar planets, not much information of precise objects could be found except gases because the tools we have to see outer planets are limited.
