The man-made objects which orbit the Earth are:
(A) Moon
(B) U.F.O
(C) Artificial satellites
(D) Asteroids
Solution
Hint We know that a satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth). NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. Based on this we have to answer this question.
Complete step by step answer
It is known that satellites that are man-made are called artificial satellites. Those are launched from Earth into space so that those revolve around or orbit the Earth to collect and send various information.
Thus, we can say that artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. Satellites can even have people in them, like the International Space Station and the Space Shuttle. The first artificial satellite was the Soviet Sputnik 1 mission, launched in 1957.
Currently there are over 2218 artificial satellites orbiting the Earth. Heliocentric orbit: An orbit around the Sun. In our Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris.
These satellites are called artificial satellites.
Hence, the correct answer is option C
Note: We know that asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across. In total, the mass of all the asteroids is less than that of Earth's moon. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt, a region between the orbits of Mars and Jupiter. Some asteroids go in front of and behind Jupiter. They are called Trojans. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade. If something slows an asteroid, it may "fall" towards the Sun, towards Mars, or towards Jupiter. Other scientists believe that the material making the asteroids never came together into a planet at all.
