how big is jupiter compared to earth

Jupiter is enormous compared to Earth: it is a bit more than 11 times wider, over 300 times more massive, and can fit about 1,300 Earths inside its volume.

Basic size comparison

• Jupiter’s diameter is about 142,800 km, more than 11 times Earth’s 12,700 km diameter.

• Line up Earths side‑by‑side, and it would take roughly 11–11.2 of them to span Jupiter’s width.

• In terms of volume, roughly 1,300–1,321 Earths could fit inside Jupiter.

Mass and gravity

• Jupiter’s mass is about 318 times that of Earth, making it more massive than all the other planets combined by a factor of about 2.5.

• Despite that huge mass, Jupiter’s cloud‑top gravity is only about 2.5 times stronger than Earth’s because it is a low‑density gas giant rather than a dense rocky world.

Surface and “feel” of scale

• Jupiter’s total surface area is over 120 times Earth’s, so if you could “unwrap” both planets, more than a hundred Earths would be needed to cover Jupiter.

• A common visual analogy: if Earth were the size of a small coin, Jupiter would be closer to a large dinner plate in comparison, showing just how huge the gas giant really is.
