No, that was done by Johannes Kepler.
All planets have elliptical orbits.
Newton's law of universal gravitation can be used to show that all planets orbit the sun in an elliptical path. Each planet also has gravity and keeps their own moons orbiting around them also in elliptical orbits.
No the planet's orbits are not VERY elliptical but yes, they are somewhat elliptical. They are not just rotating in a circle. More like an oval.
elliptical in a ovalish shape
He discovered them orbiting the Planet.
That they followed elliptical orbits.
Galileo Galilei was the first to discover this.

Planetry orbits are elliptical. Most planet's orbits are nearly circular apart from Mercury and Pluto.
Johannes Kepler in 1619 first realized that planetary orbits were elliptical rather than circular.

No because the planetary orbits are elliptical
