Does Mercury have 17 moons?
Mercury, the smallest and innermost planet, has no moons, or at least none that can be detected to a diameter of 1.6 km (1.0 mi). For a very short time in 1974, Mercury was thought to have a moon. Venus also has no moons, though reports of a moon around Venus have circulated since the 17th century.

Does Mercury have 62 moons?
A perfect example of this is Earth, which is able to hold The Moon in its orbit, in the face of the overwhelming gravity of the Sun, because it orbits within Earth's Hill Sphere. Alas, this is why Mercury has no moons of its own.

The planet Jupiter's four largest moons are called the Galilean satellites after Italian astronomer Galileo Galilei, who first observed them in 1610.
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.
Are there 170 named moons?
Scientists usually refer to them as planetary satellites (human-made satellites are sometimes called artificial moons). There are about 170 moons in our Solar System. Most of them are in orbit around the gas giants Jupiter and Saturn.
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.
What planet has 62 moons?
Saturn’s Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena. The moons shape, contribute and also collect material from Saturn's rings and magnetosphere.
What planet has 3 moon?

Will Earth lose the Moon?
Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.
Do we have 2 suns?
Our Sun is a solitary star, all on its ownsome, which makes it something of an oddball. But there's evidence to suggest that it did have a binary twin, once upon a time.

What planet has over 1000 rings?
Saturn Saturn is surrounded by over 1000 rings made of ice and dust. Some of the rings are very thin and some are very thick. The size of the particles in the rings range from pebble-size to house-size. Scientists believe that the particles came from the destruction of moons circling the planet.
Which planet has 150 moons?
Saturn Yes, Saturn has at least 150 moons and moonlets in total, though only 53 of these moons have been given official names. Most of these moons are small, icy bodies that are little more than parts of its impressive ring system.
Does Saturn have 83 moons?
Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming. Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena.
What planet has 81 moons?
Jupiter Jupiter has more natural satellites than any other planet in the solar system. By the latest count, there are 81 Jovian moons, the last two being officially recognized in June 2017.
Will the Sun explode?
No supernova, no black hole Our sun isn't massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun.
Do we have 2 moons?
The earth has picked up a second moon. It's not very big. In fact it's almost impossible to see. Astronomer Kacper Wierzchos says it's an asteroid that's roughly 9 feet in diameter that got captured by the earth's gravity about 3 years ago.
What is Earth’s twin?
Venus Thanks to Venus Express, Taylor now describes Venus as “Earth's twin, but separated at birth.”
Does Earth exist in Star Wars?

Is Earth losing water?
Water flows endlessly between the ocean, atmosphere, and land. Earth's water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
How long will the earth last?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
Will Earth lose the moon?
Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.
Does Earth have 2 suns?
The placement of the planets appears out of whack compared to other systems, and it's missing the most common planet in the galaxy, the super-Earth.) So, if not for some cosmic event or quirk, Earth could have had two suns. But we don't.
