Did the Earth used to 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.
Does Earth have 1 or 2 moons?
The simple answer is that Earth has only one moon, which we call “the moon”.

What if Earth had 2 moons?

Does Earth have 3 moons?
After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Scientists discovered two extra moons of Earth apart from the one we have known for so long. Earth doesn’t have just one moon, it has three.
Do any moons have moons?

What if the sun exploded?
The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
Can a moon have moons?
Yes, it is possible for a moon to itself have moons and/or rings, and there are a few places where scientists have suggested that this is (or was) the case.

Will the Sun become a black hole?
Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. In some 6 billion years it will end up as a white dwarf — a small, dense remnant of a star that glows from leftover heat.
Can we live without the Sun?
Without the Sun’s rays, all photosynthesis on Earth would stop. While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
What if the Earth had two moons?
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth’s rotation, causing the day to get longer.
