Does it rain diamonds on Neptune?
The postdoctoral research at NASA's Goddard Space Flight Center explained that the high amount of methane in both Uranus and Neptune is the key factor why it rains diamonds on the two planets.
Is Neptune all water?
Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.
Does Pluto have moons?

Can moons have moons?
Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.
How old is the Earth?

What was Uranus hit by?
The seventh planet from the Sun, Uranus has the third-largest planetary radius, and scientists believe that around four billion years ago it was hit by a huge object, likely made of rock and ice.
What planet has 9 moons?
Jupiter's menagerie of moons includes the largest in the solar system (Ganymede), an ocean moon (Europa) and a volcanic moon (Io). Many of Jupiter's outer moons have highly elliptical orbits and orbit backwards (opposite to the spin of the planet).
Did the Earth have 2 moons?
Earth once had two moons, which merged in a slow-motion collision that took several hours to complete, researchers propose in Nature today. Both satellites would have formed from debris that was ejected when a Mars-size protoplanet smacked into Earth late in its formation period.

Which planet is full of diamonds?
For centuries, astronomers have been fascinated by Saturn. After all, she has been hailed as the precious jewel of our solar system, one of the most beautiful planets. And while her rings have mesmerised us for centuries, it is even more amazing to realise that it quite literally rains diamonds out there!

Does Mars have moons?
PhobosDeimos Mars/Moons Mars' moons are among the smallest in the solar system. Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. No known moon orbits closer to its planet. It whips around Mars three times a day, while the more distant Deimos takes 30 hours for each orbit.
What is Eris moon called?
DysnomiaEris / Moon Eris's moon is named Dysnomia, the demon goddess of lawlessness and the daughter of Eris. This is fitting since the discovery of Eris led to the demotion of Pluto from planet to dwarf planet amidst continuing debate in the science community and the public.
Has Mars got a moon?

Who created Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Do you age in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
What if Saturn crashed into Earth?
However, if Saturn were to come closer to Earth (after chucking the Moon out of orbit), imagine the scale of ocean tides then. There would be huge… no, apocalyptic tidal waves that would rage all over the planet and destroy everything in their path.
What planet crashed into the Earth?
Theia Theia is a hypothesized ancient planet in the early Solar System that, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris gathering to form the Moon.
What planet has 21 moons?
Uranus In 1999 three new moons were discovered orbiting Uranus, a great gasball of a planet about 2 billion miles from Earth. The discovery raised the number of Uranian moons to 21, the most, as far as is known, in the skies of any planet.
