Pluto, which is a planetesimal, not a planet, orbits the star called Sol. Sol gives its name to our Sol-ar system, and is often called, "The Sun."
I'll assume you mean: "... as opposed to a circular orbit". That is caused by the fact that for a circular orbit, a planet needs a VERY PRECISE SPEED. Change the speed slightly (at a particular point in the orbit), and the orbit immediately becomes elliptical.
Mercury is the second smallest planet @ 3,031 miles (4,878km) in diameter after the smallest Pluto @ 1,413 miles (2274 km) in diameterno it is not the biggest planet the biggest planet in our solar system is Jupiter
A planet is an object that orbits a star, has enough gravity to make itself mostly round, and has cleared other objects out of its orbit. A satellite is an object that orbits another object that is itself orbiting a star. The object may be a planet, dwarf planet, asteroid, or comet.
Planets and stars are not the same. Venus is the closest planet, on average. The sun is the closest star.

Pluto is not a star. It was never declared a star. It is a dwarf planet. It had been regarded as a planet, but due to its size and its orbit, it is now classified as a dwarf planet, but not a star.
Pluto, the dwarf planet, is the smallest planet in our solar system. In 2006 scientists confirmed that Pluto was a dwarf planet. They confirmed this because Pluto does not have a clear orbit around the sun. The things that a planet must have in order to be a planet is that it MUST have a clear orbit around a star. FUN FACT: Pluto's moon is almost as big as itself! Pluto is the coldest planet in our solar planet. Pluto is an outer planet.
U answer
A planet orbits around a star, such as the Sun in our solar system. The gravitational pull of the star keeps the planet in its orbit as it travels through space.
Pluto is not a planet because it has not cleared everything from its orbit. The rules of a planet are:It orbits the SunIt is large enough for gravity to squash it into a ballIt must have cleared everything in its orbit (Pluto did not fulfill this).
A planet is in direct orbit around a central star, while a moon is in orbit around a large body (a planet) rather than in a direct orbit around a star. The moon orbits the planet, while the planet orbits the sun.
The motion of the planets are elliptical motions
No planet orbits around Saturn because planets only orbit around a star like our Sun. And Saturn isn't a star, it's a planet.
Pluto never changed to a star. In 2006 it was reclassified as a dwarf planet.
Orbit has the following two meanings:the curved path of a celestial object or spacecraft around a star, planet, or moon. (noun)move in orbit around a star, planet or moon. (verb)
it is an orbit
No, Pluto is a Drawf Planet.
