The fact that he is orbiting means he is being held by the gravitational force of the Earth. If not for that, he would be headed out of the solar system.

Why does a star's wobble indicate that a planet is nearby?
Orbiting planets exert a gravitational force that makes the star wobble in a tiny oval pattern .
Why the gravitational force is absent in space?
Gravitational force is not absent in space. In fact, gravitational force is what keeps the universe together. The planets orbit the sun based on gravitational force.
Why astronauts don't get attracted towards the gravitational force between sun and earth?
Just like every other bit of mass in the universe, an astronaut in space is attracted by gravitational forces toward the Earth, the Sun, the Moon, and every other body in the solar system, as well as toward the other astronauts traveling with him. The astronaut's motions are the result of the combination of all of these gravitational forces. Don't forget that an astronaut on a "space walk", floating "motionless" outside the Space Shuttle or the International Space Station, is still in orbit around the Earth, and also in orbit around the Sun. All of that is the result of gravitational forces between him and the Earth, and between him and the Sun.
How do you use gravitational force in a sentence?
Gravitational force is caused by acceleration due to gravity and an objects mass. Gravitational force is the same as an object's weight. Gravitational force is something scientists try to measure. Physics is an area of science where people study gravitational force. Gravitational force is important in terms of the way planets orbit the sun in our solar system.
Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
Why does an astronaut weigh less on the moon?
The astronaut's mass is the same on the moon but the gravitational force applied on the astronaut is weaker thus the astronaut appears to weigh less.
Where does force needed to keep planets orbiting the sun come from?
The force is provided by the Sun's gravitational attraction.
A freely floating Astronaut pushes another freely floating astronaut in an artificial satellite What is the force applied by the 1st astronaut on the 2nd one?
The force applied would be zero as a freely floating astronaut feels weightlessness as the gravitational force acting on him is zero.
Who was the first black astronaut and member of the air force's manned orbiting laboratory program?
Major Robert Lawrence was the first African-American to become an astronaut and he was selected to be a part of the manned orbiting laboratory project.
What forces continually changes a satellites direction?
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
When a astronaut is in space her body is acted upon by increased gravitational force from the earth?
No, it would be with a decreased force of gravity.
Is gravitational force acting on a person who falls off a cliff or on an astronaut inside an orbiting space shuttle?
Yes to both. That would include people inside the shuttle too. If the shuttle sowed down, it would fall back to earth
What is the gravitational force acting upon an astronaut when lifting off?
The actual gravitational force on the astronaut ... the force attracting him to themass of the earth ... is exactly the same as it always is, and is equal to his weight.But ... he feels as if there's more force on him, as if his weight has increased.That's because he's accelerating aboard the launch vehicle, and there's no wayto tell the difference between the force of gravity and the force of acceleration.
What force continuously changes a satellites's direction?
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
How could one decrease the gravitational force between a planet and an object orbiting the planet?
Gravitational force depends only on the masses involved, and on the distance. Thus, to DECREASE the gravitational force, you would have to reduce the mass of the planet or the object (take some stuff away from it); or increase the distance.
Why doesn't gravity pull the artificial satellites to Earth?
Gravity pulls the satellites but the orbiting satellites don't fall down towards earth because the speed with which they move balances the gravitational force i.e. Centripetal force = Gravitational force.
What force keeps a moon from orbiting a planet?
The Moon is orbiting a planet; It is orbiting the Earth. The velocity /acceleration of the Moon and the gravitational pull between Earth and Moon are in balance, so the Moon remains orbiting the Earth. Similarly the Earth and Moon , as a binary system, orbit the Sun , and the acceleration and gravitational forces are in balance. So none of us collide.
