Sedna is thought to be less than 1600 km across, which would make it very much smaller than the Earth. We do not have really good dimensions yet.
No. While we only have a rough estimate of Sedna's size, we know that it is much smaller than Earth.
Sedna's gravity is significantly weaker than Earth's gravity. Sedna is a distant dwarf planet located in the outer reaches of our solar system, and its smaller size and mass result in a much weaker gravitational pull compared to Earth.
Smaller, Mars is about half the size of Earth
The gravity on Venus is about 91% of Earth's gravity, on Mars it is about 38%, on Uranus it is about 89%, on Sedna it is about 0.6%, and on Neptune it is about 114% of Earth's gravity.
There are 8 planets Mercury (smaller than Earth) Venus (smaller than Earth) Earth Mars (smaller than Earth) Jupiter (bigger than Earth) Saturn (bigger than Earth) Uranus (bigger than Earth) Neptune (bigger than Earth) so 3 smaller & 4 bigger than Earth 37.5% smaller than Earth 50% bigger than Earth

smaller then earth

A year on Sedna is 10,500 Earth years.
Yes. There is proof. The proof is that one whole orbit for Eris is five hundred fifty seven Earth years and one whole orbit for Sedna is ten thousand Earth years.

Mercury is more than 2x smaller than Earth.
Venus is slightly smaller than Earth.
Mercury is smaller than earth.
It is smaller than earth.
