Yes, all the planets in our solar system, including Pluto, orbit the Sun in elliptical paths rather than perfect circles. This is described by Kepler's laws of planetary motion, which were formulated by the German astronomer Johannes Kepler in the early 17th century.
Kepler's first law, also known as the law of ellipses, states that the planets orbit the Sun in ellipses with the Sun at one of the two foci of the ellipse. This means that the distance between a planet and the Sun varies throughout its orbit, resulting in an elliptical shape.
While the orbits of the planets are close to being circular, they are not perfect circles. Pluto, which was formerly classified as the ninth planet but is now considered a dwarf planet, also has an elliptical orbit around the Sun. In fact, Pluto has a more pronounced elliptical orbit compared to the eight planets in the solar system, with a highly eccentric path.
So, to summarize, all planets, including Pluto, orbit the Sun in ellipses rather than perfect circles, in accordance with Kepler's laws of planetary motion.
