Top Ten Exoplanets

Space.com has compiled a list of the top ten exoplanets, or planets outside of our solar system. The list is cool to take a look at and I'll cap the top ten briefly right here, if you want to see the full descriptions go here at Space.com


Number 10:

51 Pegasus b, or Bellerphon, was the first planet ever discovered outside our own solar system, earning it position number ten.

Number 9:

Epsilon Eridani b, the exoplanet found closet to our own solar system is only about 10.5 light years away. So close that soon telescopes may be able to visually view it.

Number 8:

Planets called planemos, or sometimes described as rogue planets. These objects have no sun and are objects that never quite ignited into a star.

Number 7:

Planets such as SWEEPS-10 which orbit their parent star extremely fast. In SWEEPS-10 case, orbiting only 740,000 miles from it's star, one day is only 10 hours long.

Number 6:

Upsilon Andromeda b, is "tidally locked" to it's star, meaning one side is always facing the star. This is quite possibly the most temperature variant world in existence.

Number 5:

The youngest exoplanet ever discovered. This planet orbits star, Coku Tau 4, and is less than a million years old.

Number 4:

The oldest planet ever discovered, takes position 3. This planet is 12.7 billion years old, and proves that life could have formed very early in the existence of the universe.

Number 3:

HD209458b orbits every 3 and a half days and is losing mass to solar winds at about 10,000 tons per second.

Number 2:

189733b was one of the first planets to have it's atmosphere tested for composition.

Number 1:

The number one slot for exoplanets is taken by Gliese 581 C. This planet discovery was huge, as this was the first planet discovered which exsists in the zone of a system where life can be supported. This proves that life can exsist elsewhere, whether it's microscopic or larger is anyones guess.
