No.
All four rocky planets are much smaller than gas planets.
There is gravity on all planets. The strength of that gravity varies depending on the size and mass of each planet.
Planets are inanimate and, like all inanimate objects, they do not poop!
The average size of the outer planets (Jupiter, Saturn, Uranus, and Neptune) is significantly larger than that of the inner planets (Mercury, Venus, Earth, and Mars). They are all gas giants with diameters ranging from about 49,528 km for Uranus to about 142,984 km for Jupiter.
The planets reached their approximate current size about four and a half billion years ago.
They are all bigger
The planets of our solar system are most definitely NOT all the same size.
No
No.
They revolve. They all have individual orbits round the Sun. The orbits closely approximate ellipses.
All four rocky planets are much smaller than gas planets.
High density, small size.

The size is 100
All of the outer planets are large in size, low in density, and have very thick atmospheres made primarily of hydrogen and helium.
