Many extra-solar planets have been detected, some many light years distant, at our present stage of technology it would take many millions of years to reach them
Planet Earth weight is 5.972E24 kg. Earth, also known as the world, Terra, or Gaia, is the third planet from the Sun.
The Planet Earth is ONE planet.
Pretty much every planet has an axis, because an axis is what a planet rotates around. Any planet that rotates has an axis, and pretty much every planet known rotates.
Earth is not the heaviest planet known. In our solar system that distinction goes to Jupiter, which is over 300 times the mass of Earth. (There are also exoplanets much heavier than Jupiter.)
Eris is not a planet; it is a dwarf planet. It is much smaller than Earth.
There is no such planet known. In our solar system, the planet whose moon is closest in size to the planet which it orbits is none other than our own planet Earth. However, the Moon is still much smaller than the Earth. Pluto has a Moon that's big, but Pluto isn't a "planet" now, of course.

It's a rocky planet, but is much smaller than earth and colder.
The Planet Venus, since it is of a similar size and composition. It is also the planet which comes closest to earth.
Yes, Mercury and Venus are much hotter than us.
It is a rocky planet that is much smaller and colder than earth.
Uranus is a Jovian planet, which are much larger the terrestrial planets, like Earth.
