It takes five good observations to find the orbital elements for a planet. The observations need to be taken over enough time for the planet to cover a good fraction of the orbit. That allows an ellipse to be fitted to the measurements.
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.
Mercury: Elliptical Venus: Elliptical Earth: Elliptical Mars: Elliptical Jupiter: Elliptical Saturn: Elliptical Uranus: Elliptical Neptune: Elliptical All planets revolve around the Sun in elliptical orbits, with the Sun located at one of the two foci of the ellipse.
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.
elliptical
Yes, the distance from the sun is variable for anything with an elliptical orbit.
