in some parts of its orbit it is much closer to the Sun than in other parts.
Pluto
Comets go around the Sun in a highly elliptical orbit.
Plutos orbit is highly eccentric - during one rotation of the sun its distance from the sun can vary considerably. For 20 years of each of its orbit - a small fraction, it is closer to the sun than Neptune, which has much more of a regular orbit. Neptune is now the furthest planet again as of 2006. This time its for another reason - Pluto is no longer classed as a planet, but is instead a Dwarf Planet.
Mercury's orbit is moderately eccentric, at 0.2056, while Venus's orbit is the least eccentric of any planet in the solar system, at 0.0067. Mercury's inclination is at 7º, while Venus's is at 3.39º.
because its orbit was highly eccentric and used to intercede the orbit of Neptune. that is why Pluto is no more a part of our solar system as it collided with Neptune and exploded.
It deviates from a perfect circle by a considerable amount.
The least eccentric orbit is Venus The most eccentric orbit is Pluto (aside from Pluto, Mercury)
pluto
Pluto
The eccentric old man washed his hands with pea soup. Pluto's orbit is much more eccentric than the orbit of any major planet.
Yes, some do.
comet
Comets are small bodies of rock and ice which are in a highly eccentric orbit directly around our sun.
The minor planet Pluto has an orbit which is inclined to the plane of the ecliptic. It is also a highly eccentric ellipse, causing it sometimes to pass inside the orbit of Neptune.
Comets go around the Sun in a highly elliptical orbit.
The orbit becomes more eccentric until the orbit becomes almost a strait line.
