“All known gas giants, like Jupiter and Saturn, have solid cores. These cores are either rocky or metallic, and aren’t completely solid throughout, with some of the core being comprised of molten metal and rock.”
I would say, anything whose spacetime geodesic (orbital/freefall path) intersects the spheroid defined by the surface of the Earth. Though by this definition, a comet on a 100-year collision course is already “on Earth”, so I’m not sure if that’s reasonable.
technically, airplanes aren’t on earth whilst being fast,
Technically they are still faster than cheetah on land when taking off
Technically, Neptune, Uranus, Saturn, and Jupiter aren’t planets, just clouds really far away
Actually, the gas giants do have a solid core
Has it already been confirmed or it’s still a hypothesis?
Please share any material proving it if you have any, I love space.

That’s amazing, thank you!
Which one has cloud city again?
Bespin… ahhhhhhhhhhhhhh! You got me!
Technically, it is if you count atmosphere as part of earth
you matter. light energy.
What defines being on earth? Below the atmosphere? stratosphere? Being in contact with the ground? Being more than 10m up?

In that case, technically the light isn’t either
