How big is Jupiter compared to Earth? And how can I determine that with the Laws of Gravitation?

answers:
say: If only there was some way to search the internet.

tham153 say: Jupiter's equatorial diameter: 11.209 times Earth
Jupiter's polar diameter: 10.517 times Earth
Size is unrelated to gravitational strength, you need mass. Jupiter's mass is 317.8 times Earth's mass
-
Clive say: Big in what sense? Mass or diameter? Gravity only relates to mass.
-
Ronald 7 say: Roughly about 11 times the Diameter
-
James say: Not as big as Uranus, I mean, Urmomsanus

quantumclaustrophobe say: Jupiter's diameter is about 11 times that of Earth - 88,000 miles, versus Earth's 8,000 miles. It's mass is about 317 times that of Earth - and, you can calculate this mass by how fast the moons orbit around Jupiter at their respective distances. Jupiter has a volume about 1,300 times that of Earth - so, 1300 Earths could fit inside Jupiter...

StarShine say: Like... way big! (google it, that's what your answers are going to be)

billrussell42 say: big in what sense? diameter? volume? mass?

you can measure the orbital time and distance of it's satellites, and from that calculate its mass. diameter can be determined from a good telescope. volume can be calculated from diameter.

below are the numbers.

Jupiter ♃
Mass 1.899e27 kg
Equatorial radius 71,492 km
Polar radius 66,854 km
Volume 1.43e15 km³

Earth ⊕
Mass 5.97e24 kg
Mean radius 6,371 km, 6.37e6 meters
Earth GM = 3.98e14
Volume 1.083e12 km³
