venus
Earth is a rocky planet because the gas giants are in the outer planets and earth is in the inner planet.
The planet Saturn.
blue
No, but its moon, Titan, may have volcanoes.
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.
Uranus
Uranus, the 7th planet from the sun, is bluish-green and gaseous. This is due to the methane gas in its atmosphere.
Neptune.
It is our planet Earth. Blue like place is water and green like place is continents
The planet that appears blue-green through a telescope is Uranus. Its color comes from the presence of methane gas in its atmosphere, which absorbs red light and reflects blue and green light.
Neptune
Neptune is known for its bluish appearance and is often referred to as the "blue planet" due to its vivid blue color caused by methane in its atmosphere. It is a gas giant planet with no solid surface, covered in swirling clouds and high-speed winds.
Uranus
Uranus is the seventh planet from the Sun and has a blue-green color due to methane in its atmosphere. It has an axis tilt of about 98 degrees, making it the planet with the most extreme axial tilt in our solar system.
You are describing Saturn. There are other gas giants in our Solar system, but Saturn has the rings.
The planet Earth looks blue and green from space because of its atmosphere, which contains gases like oxygen and nitrogen that scatter sunlight to create those colors.
The planet Uranus appears blue-green due to the presence of methane in its atmosphere. Methane absorbs red light, allowing the blue and green wavelengths to be more prominent, giving the planet its distinct color.
