Yes, every closed orbit is an ellipse. Circles are "perfect" ellipses, but no natural orbit could be perfectly circular.
Johannes Kepler was the person who first showed that planetary orbits are ellipses. His work, published in 1609, is known as Kepler's first law of planetary motion.
One of the discoveries that led to the modern view of the Solar System was that the orbits of the planets were ellipses. This was one of the key contributions from Johannes Kepler's laws of planetary motion, which replaced the earlier belief that planetary orbits were perfect circles.
Kepler showed that the orbits of the planets are elliptical, with the Sun at one of the focal points. This discovery led to his laws of planetary motion, which describe how planets move in their orbits.
The Moon is the planetary body that orbits the Earth.
Planets remain almost perfectly spherical as they move around the sun. The paths they follow are ellipses, with the sun at one focus of each ellipse.

Kepler realised the planets orbits are not circles; they are ellipses.

Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.

The shape of most planets' orbits around the sun, including Earth, is elliptical. This means that their orbits are not perfect circles but rather slightly elongated with the sun positioned at one of the foci of the ellipse.
Ellipses are a scientific word for the shape of an oval. for example the planets orbits are ellipses.
All closed gravitational orbits are ellipses.
their orbits
The orbits of periodic comets and the orbits of planets have the same geometric shape.Every closed gravitational orbit is an ellipse. But the eccentricity of the cometary ellipsesare almost all greater than the eccentricities of the planetary ones.
No, all orbits are ellipses. That includes the Earth's orbit.
All orbits are ellipses.
