Its orbit
That is its orbit.
All orbits are ellipses.
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.
A satellite is a small celestial object whether natural or synthetic that encircles or free floats in space a larger object such as a planet. A planet is a massive object orbiting a star in a fixed orbit. It is big enough so that its gravity makes it almost round.
Jupiter.
stars
More massive planets have more gravitational pull. If a satellite were to pass by Earth and Jupiter at the same distance from each planet, the satellite would be more attracted to start orbiting Jupiter because of its pull. The more massive a planet is the more likely it is to get a satellite to orbit it.
A super-massive black hole
is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite. it has to have sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium. It should not be confused with a minor planet.
These are bodies in orbit (around each other) due to the forces of gravity.If the barycenter (the point around which both rotate) of the system is inside one of the bodies (such as the Sun and any of the planets as well as the Earth and Moon system) then the less massive body is said to orbit the more massive one.If the barycenter is in space between the bodies it is called a binary system or double planet (such as Pluto and Charon)
Ganymede is the most massive satellite in the Solar System.
According to the General Theory of Relativity, the path of light is bent near large masses. The more massive a celestial object is the more light is bent near it.
