What holds up the planets?
everthing is weightless in space.
Does gravity affect the air we breathe?
Yes, gravity affects the air that we breathe. That is why it is harder to breathe when we go up high mountains. There is less air there. Without gravity, the air would float off into space, just as we would.
How does the earth stay up in space?
it stay up by gravity
What force holds the planets in orbit around the sun?
It's the force of gravity which acts on the planets and keeps them in their orbits. Gravity works both ways but the Sun is more massive by far so does not move very much at all. The planets are caused to accelerate towards the Sun by gravity. They move in their orbits with velocities, at any moment, at a tangent to their orbital paths. The result is that they move in a continuous curve around the Sun. If they move slightly closer they speed up, which causes them to move out again, so the orbits are stable. Potential energy and kinetic energy are being exchanged all the time for each planet but the total stays constant.
Spinning of a planet?
To stay up in space. Gravity.
What holds up the planets?
everthing is weightless in space.
Why do you have outer space?
we have outer space because what else is going to hold the planets up and not let them fall forever, that's what our sun does, and outer space holds the sun up
What holds the planets and other bodies of our solar system in orbit around the sun?
They are held by the force of gravity, specifically the gravitational pull of the Sun. Just as gravity holds people to the Earth's surface, and the Earth holds space stations in orbit, so the Sun holds the planets in their orbits. The orbital velocity of the planets (momentum) keeps them from falling into the Sun, while the Sun keeps them from flying off into space. This combination of counteracting forces also keeps the Earth its current distance from the Sun. Mercury, closer to the Sun, travels more quickly to balance the stronger pull of the Sun.
Why does space have no oxgen?
Because gravity tends to bring things together into either stars, planets, or the like, and the gravity of these sweep up anything in their vicinity, leaving vacuum.
What keeps up the and the planets?
Gravity
How do you tie up spaceship in space?
Well usually gravity holds it down such as orbit, or it just stays in space. In space there are not any forces acting then it will not move if the rocket is not travelling.
How does gravity play a role in gas giants?
gravity is what holds the gas giants. As the gas giants are made up of gases...gravity must hold them in place or they will run off to space..that rhymes.
What holds the sun up?
The sun is in the milky way galaxy. In the center of the galaxy is a huge black hole that holds the billions of star up. If you do not believe me go to the videos about How The Universe Works. It clearly shows proof.
What did Newton propose holds the planets up?
people
Why do planets stay up in the sky?
There is no gravity in space so they just sort of float and every planet orbits around the sun and also helps them stay in place
Is the inner core the only thing that holds the earth?
I am not sure that it makes sense to say that anything holds the Earth. The Earth is a planet in space, which orbits the sun. Gravity holds it in orbit, and gravity holds it together. The incompressible matter of which it is composed, holds up the surface, for our convenience as its inhabitants. Every layer, the inner core, the outer core, the mantle, and the crust, has a role to play in making our planet what it is.
How does the sun's gravity affect the earth?
The suns gravity can only be part of the answer as to its affect upon the earth. If there were only the suns gravity then we would be pulled into it. Thankfully we have all of the other heavenly bodies which work together to keep us where we are in our own particular place in space.
