Exoplanets are planets that orbit a star other than our sun . The prefix exo comes from the Greek and means outside; these worlds are far, far outside our own solar system. Astronomers have confirmed more than 4,000 exoplanets orbiting distant stars, with at least 1,000 more more awaiting confirmation.
What makes a planet an exoplanet?
All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit.

What is an example of an exoplanet?
Another interesting example of exoplanets are known as lava worlds, Earth-sized exoplanets with extremely high temperatures. One example is known as Kepler-78b , which orbits its star at only 1% of the distance from Earth to our Sun! ... The closest discovered exoplanet which could possess life is just 4 light years away!

Can humans live on a Super Earth?
To live on a Super Earth would require super strength . If Earth were 10 times larger, gravity would be 10 times stronger. This is based on the formula of Surface Area = Mass/Radius squared. ... Technically, our skeletons can withstand a force more than 90 times that of the Earth’s gravity, but only when standing still.
Is the diamond planet real?
Another planet, 55 Cancri e , has been called a “super-Earth” because, like Earth, it is a rocky planet orbiting a sun-like star, but it has twice the radius and eight times the mass. The researchers who discovered it in 2012 concluded that it was carbon-rich, making an abundance of diamond likely.
Can we live on Neptune?
