There are many reasons why the 55 Cancri B was one of the most interesting planets discovered. Firstly, it one of the relatively new planets as it was discovered in April 2006. The fascinating aspect of these planet’s discoveries is that it is a two-star, multiple star solar system. This is the highest number of confirmed planets that are orbiting one star apart from the sun.

Discovered in March 2007, the V391 Pegasi b is one of the new planets. It is amongst the interesting planets’ discoveries because of where it orbits. V391 Pegasi b was found orbiting a white dwarf star. The meaning is that it was once swallowed up by the star and survived. This bodes well for the Earth which is likely swallowed up by our sun in 5 billion years time.

6.) µ Arae c

The HD 209458 b was an interesting discovery as it was the first exoplanet in which the atmospheric composition was known, thanks to its perfect alignment with our line of sight. The planet’s atmosphere contains sodium, methane, carbon dioxide, and some water vapor. This planet was also the second planet that has been revealed to possess organic compounds.

2.) Fomalhaut b

Gliese 581-b makes the list as one of the top ten planets ever discovered and ranks top partly because of how similar it is to our planet. The Gliese 581-b is startlingly similar to Earth despite being 7-14 times its size. Its orbit is within the habitable zone of its solar system making it capable of containing life. The possibility of intelligent life forms similar to ours is also extremely high.

These are the top 10 planet discovered. Our focus has primarily been on the new planets – discovered within the past two decades – which have greatly improved our understanding of our universe.
