Yes, every closed orbit is an ellipse. Circles are "perfect" ellipses, but no natural orbit could be perfectly circular.

Who was Person who first showed that planetary orbits are ellipses?
Kepler
What kind of orbits do most planets have?
ALL closed gravitational orbits are ellipses.
Does Jupiter orbit in a circle?
No, all the planetary orbits are elliptical.
Kepler showed that the orbits of the planets are?
Ellipses.
Shape of planets' orbits discovered by Kepler?
ellipses.
What shape are most planets' orbits around the sun in specific the earth?
ALL planetary orbits are ellipses.
Who was Person who first showed that planetary orbits are ellipses?
Kepler
According to the three laws of planetary motion what are the shapes of planetary orbits?
ellipses, with the sun at one focus of the ellipse
What is the difference between Copernicus and Kepler description of planetary orbits?
Kepler realised the planets orbits are not circles; they are ellipses.
How did Kepler expand on Copernicus' ideas?
Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.
What kind of orbits do most planets have?
ALL closed gravitational orbits are ellipses.
Who discovered ellipses?
The ellipses were discovered in the 17th century by one Johannes Kepler. Johannes Kepler discovered that the orbits along which the planets travel around the Sun are ellipses with the Sun at one focus, in his first law of planetary motion.
What are ellipses?
Ellipses are a scientific word for the shape of an oval. for example the planets orbits are ellipses.
What is the shape of asteroids orbit?
All closed gravitational orbits are ellipses.
What of the planets are ellipses?
their orbits
What is the shape of the orbit a comet has?
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.
Who said the planets traveled in oval orbits?
Everyone from the ancient Greeks on knew that the planets move in oval-type orbits, which were simulated by systems of circles. Later, after years of hard work, Johannes Kepler published the laws of planetary motion in 1618 which showed that the orbits are more accurately represented by ellipses, and each planet has its own ellipse with the Sun at one focus. Ellipses make very good approximations to the actual orbits of planets, but the gravitational effects of the other planets, especially Jupiter, mean that the planets depart slightly from true elliptical orbits. That is taken care of by regular updates to the orbital elements of the planets, which are numbers which describe the sizes and shapes, orientation and inclination of all the planets' elliptical orbits.
