Venus
is sometimes called Earth's twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.
Why is Mars called Earth's twin?
Several billion years ago when the planets and the Solar System were formed, scientists believe that
Mars was very similar to the Earth
, with a substantial atmosphere and a surface partially covered by water. Even today surface fissures are visible on the planet, presumably caused by running water.

Venus
has been called Earth's “evil twin” because it is about the same size as Earth and probably was created out of similar stuff; it might have even had at one time oceans of liquid water. But Venus appears to have suffered a runaway greenhouse effect.

What planet is Neptunes twin?

Uranus
and Neptune are in fact so similar that they are often called planetary twins.

between 1.5 and 4.5 billion years from now
. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability.
Do we have evil twins?

Can we live on the sun?
But if you take a look around, there's nothing here for you to actually land on, because

. It's just a giant ball of hydrogen and helium gas. … They're cooler regions of gas, some as large as the entire Earth.

Deep within Neptune and Uranus
, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. … Beyond the lingering mystery of the diamond rain, there's a big loss in our failure to study Uranus and Neptune inside and out.
Which planet is nearest to sun?
