In our solar system, four, all four inner planets. Mercury and Venus have no moons, Earth has one and Mars has two.
Four moons of Jupiter, also known as the Galilean moons, can be seen with a pair of binoculars. They are named Io, Europa, Ganymede, and Callisto. These four moons were first observed by Galileo Galilei in 1610 and have become famous objects of study in astronomy.
four moons
Four of the eight planets in the solar system, Jupiter, Saturn, Uranus, and Neptune, are what we call gas planets. The other four, Mercury, Venus, Earth, and Mars, are solid objects as are all the moons in our solar system.
It was his observation of four of the moons of Jupiter.
The four main moons all look about the same brightness as seen from Earth, and they are all at about the same distance from the Earth. That means that their brightness seen from Jupiter would depend on their distances from Jupiter.
Pluto has four known moons, four times as many as the Earth.
Jupiter has four moons that orbit it. the names of these moons are IO (eye-oh) Callisto, Europa and Ganymede.Time taken for the moons to orbit Jupiter:IO- 1.7 Earth yearsCallisto- 16.7 Earth yearsEuropa- 3.5 Earth yearsGanymede- 7.1 Earth years
In our solar system, four, all four inner planets. Mercury and Venus have no moons, Earth has one and Mars has two.
His primary discovery was the four larger moons of Jupiter, which are called the "Galilean moons" in his honor. It was absolute proof that Aristotle had been wrong about everything in the heavens going around the Earth; here were these four moons going around Jupiter, not the Earth!

Yes, all four of Jupiter's large moons can be seen with binoculars.
Jupiter, Saturn, Uranus and Neptune each have more than four. Mars has two, Earth has one, Venus and Mercury don't have any. No planet has exactly four moons. Pluto, a minor planet, has four known moons: Charon, Nix, Hydra, and P4.
The moon can be found in space. Moons will orbit around planets that have moons. Earth has one moon that gives four different phases each month.
they dont
All of the inner planets; Mercury, Venus, Earth and Mars have less than 3 moons, while all four outer gas giant planets have many moons.
Some planets have no moons at all, such as Mercury and Venus; some, like Earth, has only one. Mars has two tiny moons, and Jupiter has four large moons and 60 or so small ones.
