What happens when a satellite is in orbit around the Earth?

With the correct launch speed the satellite continues in its falling orbit around the Earth. It is just a matter of setting the horizontal speed of the satellite such that the gravitational pull of the Earth (at the given height) tugs it round on its orbital path. In this sense, the satellite just keeps going itself .

What keeps a satellite like the moon in orbit around the Earth?

Gravity–combined with the satellite’s momentum from its launch into space–cause the satellite go into orbit above Earth, instead of falling back down to the ground.

What keeps the moon traveling forward in its orbit?

The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth’s oceans to form a tidal bulge. Due to the rotation of the Earth, this tidal bulge actually sits slightly ahead of the Moon.

How many artificial satellites does Earth have?

Of the 3,372 active artificial satellites orbiting the Earth as of January 1, 2021, 1,897 belong to the United States. This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 412. Artificial satellites are human-made objects deliberately placed in orbit.

What are artificial satellites used for?

Artificial satellites can be used for: communications – satellite television and phone calls; Earth observation – including weather forecasting, tracking storms and pollution, spying and satellite photography; navigation – including the Global Positioning System (GPS);

Does the Earth have more natural or more artificial satellites?

Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.

Which of the following are uses for the artificial satellites orbiting the Earth?

Uses of artificial satellites

• They are used in communication.
• They are used in weather forecasting system.
• They are used in GPS (Global Positioning System)
• They are used to transport instruments and passengers to the space to perform experiments.
