because of it's own gravity
Our Earth is not in a falling orbit.
Yes, it does.
No.
As a noun: The rocket placed the satellite into a high Earth orbit. As a verb: The satellite had to travel very fast to orbit the Earth.
Meteors travels through earth. While the meteors travel towards the earth they go around the orbit.
the Hubble doesn't orbit the earth, it orbits the sun slowly fling farther and farther into space.
Jupiter has an orbital period of 4,331.5 Earth days or about 11.86 years. Its orbit is much longer than Earth's, and it also moves more slowly in its orbit. Jupiter's orbit is roughly 11.86 Earth years long.
Because it does travel across the sky, the moon orbits the earth, the earth doesn't orbit the moon.
Yes. The Moon travels in orbit around the Earth, at the same time that the Earth travels in orbit around the Sun, at the same time that the Sun travels in orbit around the Milky Way, etc.
In distance, Venus has a smaller distance to travel than The Earth
An orbit is the path a planet takes around the sun. Earth's orbit is an ellipse. It takes the Earth one year to travel along the elliptical path around the sun.
This depends on where the astronauts were headed to, If going to the moon, then no they do not leave earth's orbit. But if astronauts were to go to Mars, then yes. To go to other planets and to travel through space, Astronauts will leave Earth's orbit. When traveling to space from earth, Astronauts leave the atmosphere and will leave the orbit if necessary and if the travel distance is far enough.
