According to NASA and other professional/ non-professional sources, Planet X does not exist. However, it were to have eluded human detection, it would most likely be comprised of a rocky, frozen gas surface. Pluto has frozen liquid nitrogen for part of its surface composition, so it's relatively likely Planet X would be similarly comprised of that too.
The planet Saturn.
The Earth is made up of gases such as carbon dioxide,air,oxygen,gravity,water and much more.They all came out of Attoms from stars that exploded which is called a "supernova"(WE ARE MADE OUT OF ATOMS"
The earliest humans to reference the ground called it earth (in their languages, of course). Over time, this has spread to reference the entire planet, rather than just the ground in one spot. Other popular names include Terra Firma and Gaia.
I think that the Earth looks blue from outer space by an astronomer's eye is because the Earth is 75% water and 25% land. Since water is blue and there is a great quantity of it on the Earth, you spot the blue area first.
Up to now, Earth is the only planet in our solar system that can sustain life as we know it.
No there is no such thing as planet x. It is just a made up thing. OK this is a new person now and planet x is real but it is usually called The Destroyer. oh and it exists but its not going to ruin the world or whatever!
The planet that is made up of rocks is Neptune
the planet mars is made of rocks and air
Planet X is a hypothetical planet beyond Neptune that has been proposed to exist in the outer reaches of our solar system. It has not been directly observed, but its existence has been theorized to explain anomalies in the orbits of outer planets. Scientists are still searching for evidence of such a planet.
Each outer planet is made up of gas
Its almost entirely made up of Hydrogen and Hemium.
The surface of planet Earth is made up of 71% water.
It is made up of the material which makes up the planet.
The answer is Pluto. Pluto isn't a planet anymore so there is no planet made up of rock and ice.
Gas
Planet X was a hypothetical planet which was searched for after the discovery of planet Neptune. `Planet-X` does not exist.
Yes and no. "Planet X" is a designation given temporarily to any new planet with no name. It does not refer to a specific planet, and once a planet is given a name, 'Planet X' is discarded as a title. Several planets, including Pluto, have been referred to as "Planet X."Supporters of the Nibiru Cataclysm Theory sometimes claim that "Planet X" is NASA's method of keeping "Nibiru," a mythical, large planet-like object, secret, as part of a cover up. There is no scientific foundation for this "theory."
