What else can I help you with?
What outer planets have periods of rotation shorter than earths?
They all have.
Which planets have a surface gravity greater than earths?
All 4 gas giants : Jupiter, Saturn, Uranus, Neptune.
How many stars with planets?
There are more than 300 known stars with known planets, and the list gets longer all the time.
What is the difference between planets that rotations time are shorter than earth to planets rotation time that are longer than earth?
The outer planets all rotate faster than the inner planets. Each of them has a rotational period shorter than an Earth day. All of the inner planets have rotational periods longer than one Earth day. The outer planets are mostly made up of hydrogen, helim, and ice, and they are much larger than the inner planets which are mostly iron and various types of rock.
How big is the biggest planet?
Jupiter has the largest diameter of all the planets in our solar system, 142,985km at the equator (11.2 time that of earths), though its volume is greater than all of the other planets combine.
What is the characteristics of the outer planets?
All outer planets have a gaseous atmosphere and are larger than planets the inner planets it also takes them longer to rotate the sun they are typically colder and have more moons.
What is shape and size of the planets?
Planets, by definition are all approximately spherical in shape, though their axial rotation often means that they are oblate spheroids (look like `squashed spheres`, longer across the equator than from pole to pole). The size of the planets varies; Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12104km or 0.9488 x Earths Earth's diameter = 12756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths
Which planet has the least mass?
Mercury is the least massive of all the planets. The least massive planet is Mercury (0.055 Earths). However, the planet with the weakest gravity is Mars. I am of course not treating Pluto as a Planet (as it is no longer categorized as a planet), if I were to count Pluto then it would be the least massive ( 0.0021 Earths).
What do the the outer planets have in common?
They are all gas planets. They are all quite large and made from gas, so there is no real surface like that of earths.
Which planets have a year longer than the Earth?
All the planets further away from the sun than Earth is
Is Jupiter bigger than all the other planets together?
Yes. It is larger by both volume and by mass.Jupiter is only about 30% larger in diameter than Saturn, but its volume is half again that of all other planets combined, more than 1320 times the volume of Earth.But Jupiter is also around 2.5 times more massive than all of the other planets in our solar system put together (this also includes the Plutonian worlds). Jupiter's mass is equal to just under 318 Earths.If we took the next 4 planets in terms of size we would haveSaturn (95 Earths),Uranus (14.5 Earths),Neptune (17 Earths) - (Neptune is smaller but denser than Uranus)Earth (1 Earth),we see that the mass combined of these four is only 127.5 Earths, The remaining planets Venus (0.8 Earth) , Mars (0.1 Earth) and Mercury (0.055 Earth) add very little to the total mass of planets excluding Jupiter.(for mass comparisons, see the related link below)
Which of the outer planets has a surface more similar to the inner planets than to the outer planets?
Neptune has a surface more similar to the inner planets than to the other outer planets. It is primarily composed of rock and ice, similar to the composition of the inner planets, whereas the other outer planets are predominantly gas giants.
