Planets Moons facts

While investigating facts about Planets Moons Names and Planets Moons Number, I found out little known, but curios details like:

The moon is 1/400th the size of the sun but also 1/400th the distance from Earth which results in the moon and the sun being the same size in the sky, a coincidence not shared by any other known planet-moon combination.

how many planets have moons?

The sun and the moon look to be the same size because the diameter of the sun and moon and the distance to earth both share a 1:400 difference, making them look the same size, this has not been seen with any other planet-moon combination

What planets have moons?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what planets have no moons. Here are 50 of the best facts about Planets Moons And Stars and Planets Moons Count I managed to collect.

An exoplanet known as J1407; a planet with a ring system so huge, it is 200x larger than Saturn's. If it took the place of Saturn in our solar system, it's rings would be brighter and more prominent than the moon in the Earth's sky.
You could fit all the planets in between Earth and the moon and still have room left over to spare.
A man who would later become the president of Mormon church once declared, "We will never get a man into space. [...] The moon is a superior planet to the earth and it was never intended that man should go there. You can write it down in your books that this will never happen"... in 1961.

We're the only planet to experience total solar eclipses. And it's entirely coincidental, because the sun just happens to be 400 times larger than the moon while also being 400 times farther away. Making them appear the same size in the sky.
In 20-70 million years, Mars' moon Phobos will get close enough to the surface of the planet that it will be ripped apart by the tidal forces. The resulting debris will most likely give Mars a planetary ring.
The Milky Way has several "satellite galaxies", smaller galaxies that orbit our galaxy like moons to a planet.
Triton, the largest moon of Neptune, is the only moon in our solar system with a retrograde orbit - an orbit in the opposite direction its planet, and is thus thought to be a dwarf planet that Neptune caught from the Kuiper belt.
One of Jupiters 62 moons, Europa, is thought to have twice as much water as Planet Earth

All those sites where you can 'name a star' are ripoffs. The IAU dissociates itself entirely from the commercial practice of "selling" fictitious star names or "real estate" on other planets or moons in the Solar System."

The Earth and Moon were likely formed when a Mars-sized planet, Theia, collided with Gaia (the early Earth).

Earth has one large natural satellite, known as the Moon and sometimes referred to as Luna. It probably was formed when a large body about the size of Mars collided with Earth, ejecting a lot of material from our planet into orbit and formed the Moon approximately 4.5 billion years ago.

There is a dwarf planet called Orcus that is referred to as the "anti-Pluto" because its orbit is almost a mirror image of Pluto's and, like Pluto, it has a proportionally large moon.

Interesting facts about planets moons

Neptune has at least 14 moons, with the largest being Triton, discovered by William Lassell in 1846 one day after the discovery of Neptune. The most distant moon of Neptune is Neso which takes 26 years to make one trip around the planet.

Neptune has 14 known moons including Nereid, Proteus, Triton, Thalassa, Despina and Galatea. Neso is so far from Neptune it takes it 26 years to orbit the planet only once.

Zeus/Jupiter (God) had many love affairs, and Jupiter's (Planet) moons are named after them

The discovery of Europa and the other 3 Galilean moons, lo, Ganymede and Callisto, is what eventually lead scientists to the discovery of a sun-centered Solar System. Before this discovery, it was believed that the earth was the center and the planets orbited around the earth.

Space is really really empty. If you add up the diameters of all the other planets + Pluto in our solar system ( 382,367km they )fit in the gap between the earth and the moon (384,400km)

There are around 216 tonnes (476000 lbs) of man-made objects on the surfaces of other planets, moons and comets

You could fit all the planets in the solar system between the Earth and the Moon, and still have about 4000 km to spare.

Up to half of Earth's water is older than the Sun. Much of the water on our planet and around the solar system started out as tiny grains of ice floating in interstellar space. Ice found between stars is deuterium-rich, and apparently made its way into planets, moons and comets intact.

A Pluto-sized world, astronomers discovered Eris in 2003. It takes icy Eris 557 Earth years to complete a single orbit around the sun. All the asteroids in the asteroid belt would fit inside Eris. However, like Pluto, Eris is still smaller than the Earth's moon.

Titan orbits Saturn at a distance of about 759,000 miles (1.2 million kilometers), which takes 15 days and 22 hours to complete a full orbit. It is tidally locked like other moons around their primary planet, so it has a rotation period that is the same as its orbital period. That means it orbits Saturn in the same length of time that it turns on its axis.

The first model that explained how classical planets wandered was the Eudoxan planetary model. The classical planets include the Moon, Mercury, Saturn, Jupiter, Mars, Venus, and the Sun.

Pluto can"t be called a planet because it doesn"t have enough mass to attract passing asteroids or meteors into itself. Pluto doesn"t behave like a moon and orbit a bigger planet.

Saturn is the sixth planet from the Sun and the second largest in the Solar System, following Jupiter. This gas giant has an average radius about nine times the Earth. It has a pale-yellow hue due to ammonia crystals in its upper atmosphere. Saturn is known to have sixty-two moons with Titan being the largest.

Callisto (one of Jupiter's moons) has about 99% the diameter of the planet Mercury, but only about a third of its mass.
