What is the farthest known planet in the universe from earth?

Answer 1

Neptune, the farthest planet away from earth in our solar system is 4.3 billion kilometers from earth.

The planet OGLE-05-390L b orbits a star about 6000 parsecs... about 20000 light years from earth. They're finding planets around other stars almost weekly... So that may change. The farthest (galaxy) we know of is a quasar whose light has been traveling for 12 billion years. That object is now about 27 billion light years from us. Since the universe is about 15 billion years old... That's as far as we can see back in time. The light from anything much further away wouldn't have had time to get to us.

Answer 2

Neptune. Pluto isn't a planet any more, having been demoted to "dwarf planet".

However, in 1995 Neptune was farther from the Sun than Pluto was. Pluto has a highly elliptical orbit, and between February 7, 1979 and February 11, 1999, Pluto was CLOSER to the Sun than Neptune was.

Answer 3

• The farthest planet from the Sun in our solar system is Neptune. It is always Neptune.*
  
• The farthest dwarf planet from the Sun in our solar system is Eris.
• The farthest known exoplanets as of 2017 are SWEEPS-11 and SWEEPS-04
  

*Pluto is sometimes closer, but Pluto is not a planet.

Answer 4

Up until 2006, Pluto was still considered the farthest planet from the Sun. Now, scientists and astronomers have proven Pluto is not a true planet, and it is a Dwarf Planet. According to the IAU (International Astronomical Union) the definition of a true planet meets these three criteria:

1. It must be an object which independently orbits the Sun
2. It must have enough mass so that gravity pulls it into a roughly speroidal shape
3. It must be large enough to "dominate" its orbit (ie. its mass must be much larger than anything else which crosses its orbit

Edit : Yes, but Pluto has a very elliptical orbit that sometimes puts it closer to the Sun than Neptune. In fact this was the case from 1979 to 1999. So the answer to the question is: NEPTUNE.

The farthest planet from the sun is Neptune (excluding Pluto) but if Pluto was considered a planet, it would be Pluto. The Planets are set up as terrestrial planets and the gas giants. The Gas Giants are the farthest after the asteroid belt. They are Jupiter, Saturn, Uranus, and Neptune (and Pluto if it was a planet). But to answer the question fully it would the 4 Gas Giants, they are the coldest.

Neptune. Pluto crosses Neptune's orbit, so, when Pluto was a planet, sometimes Pluto would be farthest from the sun, and sometimes it was Neptune. Now, Pluto is a dwarf planet, not a planet, so Neptune is always the farthest planet from the sun.

The furthest planet is Pluto(pluto is NOT a planet), or Neptune if consider Pluto not to be a planet.

The 2 Farthest Planets are Uranus and Neptune.The 2 farthest Dwarf Planets are Pluto and Eris

The planet farthest from our sun within our solar system is Neptune, a cold gas giant 30 AU (30x earth's distance from the sun), almost the size of Uranus.

Beyond our solar system we are finding new planets all the time. There is one in the constellation of Sagittarius, orbiting a star 4850 light years from us. The closest planet beyond our solar system (as of July, 2011) orbits a star named Gliese 876 in the constellation of Aquarius only 15 light years away.

Most of the exoplanets we have discovered are within a couple hundred light years, though the Kepler Mission, which has already expanded our list of planets by a factor of two, is expected to find thousands more within the next few years.
the farthest planet from the sun is neptune .

Answer 5

As of posting the answer (31 December 2017), the planets SWEEPS-4 and SWEEPS-11, both of which orbit the star SWEEPS (J175853.92−291120.6) in the constellation Sagittarius. They are approximately 27,710 light years away.

Answer 6

Pluto is not a planet.

Pluto is a dwarf planet.

Therefore, no, Pluto is not the furthest (discovered) planet from the sun.

The current furthest planet from the sun is Neptune.

Answer 7

The eight plants in order of distance from the sun are:

1. Mercury
   
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

Neptune is the furthest from the sun and the 8th planet. Back when Pluto was considered a planet it was the 9th and furthest planet.

Answer 8

So far, over 500 exosolar planets have been detected, these are planets in orbit around other stars. The furthest confirmed exoplanet so far is MOA-2008-BLG-310L, which is over 20,000 light years away. No doubt there are exoplanets in orbit among much further stars, even in those of other galaxies. Trying to identify them is a huge challenge though, due to the distances involved.

Answer 9

In our Solar System, the farthest known planet is Neptune. It is known that planets circle many other stars; so it is likely that you will find planets as far as the power of telescopes or other instruments can go.

Answer 10

The planet Neptune is furthest from the Sun.
