It was made when the big bang happen i think?

Check the link and you will find the answer for sure.
It depends on what the object is. If it orbits a planet, then it is a moon. If it orbits the sun and is made of rock and/or metal then it is an asteroid or meteoroid depending on its size. If it is primarily made of ice then it is a comet. Dwarf planets are planet-like objects that do not meet all the criteria of a planet.
Johannes Kepler determined that planets move in elliptical orbits around the sun in the early 17th century. His observations and mathematical calculations led to the formulation of his three laws of planetary motion.

Careful and meticulous astronomical measurements by the astronomer Tycho Brahe followed by numerical analysis of that data by Johannes Kepler after Tycho's death.

planets of course, or asteroids. both are rock
The Telescope
The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
Tycho Brahe made very accurate observations of the solar system. Brahe's assistant, Johannes Kepler, used the observations to figure out the shape of the planets orbits. When he used circular orbits, his calculations did not fit the observations. But after years of detailed calculations, he found that the orbit of each planet is called an ellipse. An ellipse is an oval shape.
They all have cores, made from gas and dust, have atmosphere's, orbit sun, elliptical orbits.
Galileo and also my hamsters! my best friend is Katie Jennings!
It can be natural satellites (moons), man-made satellites or small pieces of matter such as ice (rings of the outer planets).
