Comets. They spend a lot of their time moving slowly at far distances from the sun, with brief periods of time spent closer to the sun, moving at higher speeds.
Yes, some do.
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.
comet
Comets are small bodies of rock and ice which are in a highly eccentric orbit directly around our sun.
The least eccentric orbit is Venus The most eccentric orbit is Pluto (aside from Pluto, Mercury)
Comets go around the Sun in a highly elliptical orbit.
pluto
The dwarf planet Pluto has a more eccentric orbit than Mercury. Pluto's orbit is highly elongated, meaning it is more eccentric, with a high eccentricity of about 0.24 compared to Mercury's eccentricity of 0.21.
It deviates from a perfect circle by a considerable amount.
The orbit of a planet is highly eccentric when it is more elongated rather than circular. This means the planet's distance from the sun varies significantly throughout its orbit, resulting in periods of being closer and then farther away from the sun.
The body in the solar system with an orbit so eccentric that it crosses the orbit of Neptune is called "Eris." Eris is a dwarf planet located in the scattered disc region of the Kuiper Belt and has an eccentric orbit that brings it closer to the Sun than Neptune at certain points in its orbit. Its discovery in 2005 contributed to the reclassification of Pluto as a dwarf planet.
The planet with the most eccentric orbit in our solar system is Mercury. Its orbit is elongated, varying the distance from the Sun significantly. This eccentricity causes it to experience extreme temperature differences between its closest and farthest points from the Sun.
