Is there a planet with just water?
Currently, Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone.
How many planets are in the universe?
There are over 700 quintillion planets in the universe — but there’s no place like home.
What is the closest Earth like planet?
NASA considers exoplanet Kepler-452b and its star to be the closest analog to our planet and Sun so far. Though it’s 60% larger than Earth in diameter, Kepler-452b is thought to be rocky and within the habitable zone of a G-type star similar to ours.
Are there any planets with oxygen?
The planet HD 209458b is the first transiting planet discovered, the first extrasolar planet known to have an atmosphere, the first extrasolar planet observed to have an evaporating hydrogen atmosphere, and now the first extrasolar planet found to have an atmosphere containing oxygen and carbon.
How many universe is there?

Which is larger the earth or the Waterworld?
For that reason, scientists have nicknamed the planet “the waterworld”. It is a super-Earth, meaning it is larger than Earth but is significantly smaller (in mass and radius) than the gas giants of the Solar System.
Is the planet GJ 1214 b an ocean planet?
As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. For that reason, scientists have nicknamed the planet “the waterworld”. It is a super-Earth, meaning it is larger than Earth but is significantly smaller (in mass and radius) than the gas giants of the Solar System.
What kind of water is in a water world?
Because of the varying pressure at depth, models of a water world include “steam, liquid, superfluid, high-pressure ices, and plasma phases” of water. Some of the solid-phase water could be in the form of ice VII. ^ a b c d e f g h i jCharbonneau, David; et al. (2009).
