No in fact study of exo-planets suggest that they are actually very common.
No.No.No.No.
Yes. They orbit the Sun and as per Kepler's first law they follow an elliptical path. Do note that a circular orbit is a special type of elliptical orbit.
Earth's orbit around the sun is fairly typical compared to other planets in our solar system. It follows an elliptical path, with the sun at one of the foci. The shape and orientation of Earth's orbit contribute to the changing seasons and variations in solar intensity.
You are thinking of Pluto. Pluto is now designated a minor planet.
elliptical
Mercury and Pluto have the most elliptical orbits among the planets in our solar system. Mercury's orbit is the most eccentric, while Pluto's orbit is also highly elliptical due to its distance from the Sun and its eccentric orbit.
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
Yes, the distance from the sun is variable for anything with an elliptical orbit.
All planets have elliptical orbits.
It is described as a large elliptical orbit.
It is called an elliptical orbit.
