No they are not
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
No. Jupiter's smaller moons are irregular in shape.
Moons are big rocks in space so they are not created all the same way.
Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
yes
No, the planets have different number of moons, from zero to about 60-70.
Yes, I have the same moon as you do and everybody else on Earth.
No, not all planets have the same number of moons. For example, Mercury and Venus have no moons, Earth has one moon, Mars has two moons, while Jupiter has over 70 moons. The number of moons can vary from planet to planet.
No. Only the larger moons are spherical. Smaller moons do not have strong enough gravity to make themselves round and so are irregular in shape. Perfect example are Phobos and Deimos, the two tiny moons that orbit Mars.
Yes. All koalas are essentially the same shape.
Are all orbits the same shape????
No. Just like planets, moons come in all sorts of sizes, and a few very small ones aren't even round (they are asteroids captured in orbit around some planet and have an irregular shape, as in Mars's moons Phobos and Deimos).
