How do the distances between the inner planets compare to the distance between the outer planets?

Answer 1

The orbits of the four inner planets are much closer, all orbiting the sun within ¼ billion km. The outer planets are more spread out, but are much larger in size. Their distances roughly double each time as you go out from Jupiter.

Average distances of inner planets from sun;

Mercury, 57,909,175km

Venus, 108,208,930km

Earth, 149,597,890km

Mars, 227,936,640km

Average distances of outer planets from sun;

Jupiter, 778,412,010km

Saturn, 1,426,725,400km

Uranus, 2,870,972,200km

Neptune, 4,498,252,900km

Answer 2

The inner planets are considerably smaller than the four outer planets. The inner planets diameters range from 4880km (Mercury) to 12742km (earth, while the outer planet diameters range from 49533km (Neptune) to 142985km (Jupiter - the largest).

Answer 3

The inner planets have much higher densities do to them being made up of solids. The large outer planets are made up mostly of gasses making them much less dense. The outer planets are larger making them attract more dust and gas.

Answer 4

Saturn is the least dense planet, being less dense than water (0.68g/cm3). The other gas giants are less dense than the rocky planets. Mars is the least dense rocky planet while Mercury is so dense that it weighs more than any of Jupiter's moons even though it is smaller. Earth is the densest planet (5.5g/cm3) because of gravitation compression. Mercury's high density arises from it's massive core (42% of it's volume compared to Earth's 17%)

Answer 5

The rocky inner planets are more dense than the outer planets, which are made up mostly of gas and ice.
