Question

Moons come in many shapes, sizes, and types. Scientists believe that most moons in our solar system were formed from the gas and dust around planets when our solar system first formed. As the planets formed in the early solar system, they were able to capture smaller objects with their large gravitational fields and hold them in orbit. Jupiter, the largest planet in our solar system, has 79 known moons orbiting it. Earth, the planet we live on, has 1 moon. Use your knowledge of gravity to explain why it makes sense that Jupiter has more moons than Earth. In your response be sure to:

a. compare the masses of Earth and Jupiter.

b. discuss the role of gravity in the orbital motion of objects in space.

Answer 1

Answer:

hi how are you I am fine helo

Answer 2

Answer:

a)Earth's has a mean radius of 6,371 km (3,958.8 mi), and a mass of 5.97 × 1024 kg, whereas Jupiter has a mean radius of 69,911 ± 6 km (43441 mi) and a mass of 1.8986×1027 kg. In short, Jupiter is almost 11 times the size of Earth, and just under 318 times as massive.

b)Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon.
