Usually a mechanical model of the solar system with the various planets and their moons on arms driven by motors to keep the various objects in their proper relative positions. Nowadays, computer animations of this idea are more common.
there are many skills you need to have for example , looking at things in small detail, good cummuniction skills , and all that stuff. megz xxx
Isaac Newton created many of the fundamental ideas of gravity and how it works. He came up with the idea of gravity when he was sitting in his chair and an apple fell. It basically says things with mass are attracted to other things with mass and its equations helped us find, very accurately, the orbits of the planets as well as many other things simply dealing with gravitational attraction.
They are not directly related, but in general, larger planets have more moons. we can only talk about the planets in THIS solar system; while we know of a couple of thousand other planets in other solar systems, we know nothing at all about their moons. We expect to find moons, once our telescopes get better (or our spacecraft get closer) but at this point, it is mostly guesswork. From smallest to largest (by mass), the number of known moons is 0, 2, 0, 1, 27, 14, at least 150, 67. If you want to measure diameter instead of mass, swap the 27 and the 14. You should also be aware that it appears to be an oddity of our solar system that the outer planets are large and the inner planets are small, so what appears to be a slight positive correlation between size and number of moons may actually have more to do with distance from the Sun (in that ranking, the number of known moons is 0, 0, 1, 2, 67, 150+, 27, 14). In the universe as a whole there are plenty of "hot Jupiters", massive planets in very close orbit around their primary star. We have no idea how many (if any) moons any extrasolar planet has.
the universe began about 13 billion years ago. O ne moment there was nothing . the next there was a minute, unimaginably hot ball-and suddenly the space began. this is big bang. the space consists of planet earth,moons,thec sun,inner planets,outer planets , gaint palnets,comets,meteors,stars,galaxies,neblue,black holes. space study also includes space travel and exploration.
Moons.
moons, planets and comets
No. Of the five objects currently recognized as dwarf planets, two do not have moons. Those objects are Ceres and Makemake.
Solid objects that can orbit planets are called moons. Moons are natural satellites that orbit around planets in a similar way that planets orbit around stars. Moons can range in size from small rocky bodies to larger worlds with their own atmospheres.

Objects that are in orbit around planets are commonly called satellites
Planetary moons, artificial satellites, space debris, and dust particles are some examples of objects that can orbit planets. These objects can have various shapes, sizes and orbital characteristics depending on their origin and location relative to the planet.
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
Moons are thought to form from the same material as planets through a process called accretion, where smaller objects like asteroids or planetesimals are pulled together by the planet's gravity. In some cases, moons may also be captured by a planet's gravity from passing objects in the solar system.
The solar system
Moons are approximately spherical objects which orbit planets and are smaller than the planets that they orbit, although they are still relatively large objects (so an orbiting dust particle does not qualify as a moon). Since moons orbit planets, their motion around the solar system is controlled by the planets that they orbit; planets orbit the sun, and planets take their moons with them.
