Juno is currently providing data on Jupiter, and the Cassini mission provided information on Saturn until it ended in 2017. The New Horizons mission also provided valuable data on Pluto and the Kuiper Belt region.
Voyager 1 and 2 visited the outer planets and went on into interstellar space.
-Stars -Asteroids -planets And everything else in space.
The outer planets are larger.
The inner planets are smaller than the outer planets.
There are four inner planets (Mercury, Venus, Earth and Mars) and four outer planets (Jupiter, Saturn, Uranus and Neptune). So there are an equal number of inner and outer planets.
Voyager II is the first successful space probe that reached the outer planets or Jovian Planets. It is in the rule of probes that they should not reach the outer planets because it is too far and their probes might malfunction. But this Voyager II probe had a successful flight to the outer planets.
The two Voyager space probes are robotic spacecraft launched in 1977 as the first spacecraft to examine the outer planets. Both are still operating, having passed the orbits of the outer planets, and drifting toward the boundary of the solar system.
Most famously, it was voyager 1 and 2 that explored these outer gas planets and have given us so much information. Other probes have been sent to these gas giants, but these are the the probes that visited all four gas giants between them.
The Ice Giants.
Voyager 1 and 2 visited the outer planets and went on into interstellar space.
The Voyager probes were deep space probes, sent to scout out the outer planets and deep space, so they never really "landed" on any of the planets although voyager I was sent first voyager II overtook it and encountered Saturn on august 1981.
Astronomers
its not different at all they are just outer planets
-Stars -Asteroids -planets And everything else in space.
The outer planets are larger.
The outer planets are the planets that are made of gas. Each of the outer planets are mad of gas and can not hold life.
What the history about the outer planets?
