Is Pluto sometimes closer to the Sun than Neptune?
Yes, Pluto is closer to the Sun than Neptune for a ~20 year period every 228 years. The last time it was closer to the Sun than Neptune was 1979. This happens because Pluto has an eccentric orbit that is also highly inclined, Pluto's size\mass is not directly involved in this process in any way.
Distance between neptune and Pluto?
some time is February
Is Pluto orbit close circular or quite eccentric?
Pluto has a highly eccentric orbit - it's orbital eccentricity is equal to about 0.2488. As a consequence, during parts of it's orbit around the sun, Pluto eclipses Neptune's orbit, making it closer to the sun than Neptune. The last time Pluto was closer to the sun than Neptune was between February 7, 1979 and February 11, 1999.
What planet is called the outermost planet?
With Pluto now regarded as a dwarf planet, the answer is Neptune. There are times when Pluto's orbit takes it inside Neptune for about 20 years at a time out of its 248 year orbit, as it did from 1979 to 1999. So even when Pluto was considered a planet, it wasn't always the furthest away from the Sun.
Why did neptune become the farthest planet from 1979 to 1999?
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.
What was the eighth planet between 1979-1999?
The eighth planet during those years was Pluto. Its orbit crosses that of the planet Neptune. However, Pluto is now no longer considered to be a planet.
When Pluto was considered a planet why was neptune the farthest planet from the sun from 1979 to 1999?
In 1999 Pluto was considered to be a planet. From 1979 to 1999, Neptune was further from the Sun than Pluto, because of Pluto's eccentric orbit.
Which planet was the last planet from 1979-1999?
Pluto
When was Pluto closer to the sun than Neptune?
in January 1979
From 1979 to 1999 Pluto was closer to the sun than?
Neptune
Which planet orbits crosses Pluto's every 248 years?
Pluto's orbit is 248 years. Pluto has an elliptical orbit that takes it closer to the Sun than Neptune, for 20 years, out of its 248 year orbit of the Sun. So every 228 years, Pluto's orbit crosses Neptune's orbit. This last happened between 1979 and 1999.
Is Pluto sometimes closer to the Sun than Neptune?
Yes, Pluto is closer to the Sun than Neptune for a ~20 year period every 228 years. The last time it was closer to the Sun than Neptune was 1979. This happens because Pluto has an eccentric orbit that is also highly inclined, Pluto's size\mass is not directly involved in this process in any way.
What planet was farthest from the sun until 1999?
The planet that was farthest from the Sun from February 7, 1979 until February 11, 1999 was Uranus. Though Pluto was considered the outermost planet in the solar system since its discovery, its highly elliptical orbit sometimes brought it closer to the Sun than Uranus.
What planets switch places in planet order?
No normal planets actually switch orbits the way that Janus and Epimethius (Saturn moons) do in a co-orbit. Some Dwarf Planets sometimes are closer or farther from the sun than other kindred Dwarf Planets depending on their locations along their orbits. Pluto is sometimes closer to the sun than Neptune. Haumea is usually further from the sun than Pluto but sometimes is closer. Makemake has the same relationship with Haumea. Eris is usually the farthest but sometimes in its elliptical orbit is closer to the sun than Haumea.

What planet was to the farthest from the sun until 1999?
Pluto used to be the outermost planet, except that sometimes it became Neptune because Pluto's elliptical orbit is far from circular. From 1979 to 1999 Neptune was the farthest planet from the Sun and remains the farthest from the Sun today, because Pluto us no longer defined as a planet.
