# How does gravity and inertia keep planets in orbit around the sun?

## How does gravity and inertia keep planets in orbit around the sun?

The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.

## Is the gravitational pull stronger between the sun and Mars or?

Even though the sun is also very far away its gravitational pull on the planets (including Earth) is much stronger than the pull of the planets on each other because it so much larger than any of the planets. (The sun is over 1000 times more massive than Jupiter and over a million times more massive than Mars).

What is the gravitational force between the sun and Mars?

Gravity Table

OBJECT ACCELERATION DUE TO GRAVITY GRAVITY
Mars 3.7 m/s2 or 12.2 ft/s 2 .38 G
Venus 8.87 m/s2 or 29 ft/s 2 0.9 G
Jupiter 24.5 m/s2 or 80 ft/s 2 2.54
the Sun 275 m/s2 or 896 ft/s 2 28 G

### How can the sun’s gravitational pull account for the orbital motion of planets?

A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun’s gravitational pull, and the slower it moves in its orbit.

### In which path planets move around the sun?

Hint: All the planets move around the sun in an elliptical path. Each planet moves on its own path around the sun. and not in a circular motion, it is called Elliptical orbit. All the planets in our solar system move in an elongated path around the sun.

Which planet has the biggest gravitational pull?

Jupiter
Jupiter has the highest amount of gravity in our solar system. Jupiter is the largest in our Solar System, meaning it also has the highest gravity. You would weigh two and a half times on Jupiter than what you would on Earth.

#### Does sun have gravitational pull?

274 m/s²Sun / Gravity

#### What is the gravitational force between the Earth and Mars?

The gravitational attraction between the Earth and Mars is 8.7 x 1016 N. The distance between the two planets is 5.5 x 1010m. Earth has a mass of 6.0 x 1024 kg.

What is the gravitational pull on each planet?

The weight of an object is the force on it caused by the gravity due to the planet. The weight of an object and the gravitational field strength are directly proportional….Gravity on other objects in space.

Space object g, gravitational field strength (N/kg)
Mars 3.7
Ceres (dwarf planet) 0.27
Jupiter 24.7
Saturn 10.5

## Why do planets have a gravitational pull?

The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.
