Which country has the most satellites?
the United StatesNumber of satellites in orbit – major countries 2020. Of the 2,666 active artificial satellites orbiting the Earth as of March 31, 2020, 1,327 belong to the United States. This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 363.
What is a satellite answer?
A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space.
What is inside a satellite?
The satellites generally contain cameras that can return photos of Earth’s weather, either from fixed geostationary positions or from polar orbits. Communications satellites allow telephone and data conversations to be relayed through the satellite. Typical communications satellites include Telstar and Intelsat.
What is a natural satellite of Earth?
What are the types of artificial satellite?

Is an artificial satellite?
In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth’s Moon. On 4 October 1957 the Soviet Union launched the world’s first artificial satellite, Sputnik 1.
Who is the hottest planet?
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Are used for communication in artificial satellites?
Microwaves are mostly used for satellite communication, as microwaves can pass straight through the atmosphere and connect antennas on earth to satellite in earth’s orbit.
What is the difference of an artificial satellite and a natural satellite?
Natural satellite – A small or secondary planet which revolves around a larger one. Artificial satellite – A man-made object placed (or designed to be placed) in orbit around an astronomical body (usu. the earth).
What is an example of artificial satellite?
The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space. Examples of man-made satellites include the Hubble Space Telescope and the International Space Station.
How many satellites does USA have?

What is artificial satellite Short answer?
An artificial satellite is an object that people have made and launched into orbit using rockets. There are currently over a thousand active satellites orbiting the Earth. The size, altitude and design of a satellite depend on its purpose.
How many satellites India have?
From the experimental satellite Aryabhatta launched in 1975, to RISAT-2BR1 in 2019, India’s space odyssey has spanned 44 years and over 100 satellites. The below slideshow highlights India’s space launches over the years.

Do we have 2 moons?
After more than half a century of speculation and controversy, Hungarian astronomers and physicists say they have finally confirmed the existence of two Earth-orbiting “moons” entirely made of dust.
How many dead satellites are in space?
3,000 deadWhile there are about 2,000 active satellites orbiting Earth at the moment, there are also 3,000 dead ones littering space. What’s more, there are around 34,000 pieces of space junk bigger than 10 centimetres in size and millions of smaller pieces that could nonetheless prove disastrous if they hit something else.
What is the purpose of satellite?
Satellites provide information about Earth’s clouds, oceans, land and air. They also can observe wildfires, volcanoes and smoke. All this information helps scientists predict weather and climate. It helps farmers know what crops to plant.
What are the uses of artificial satellites?
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.
What are two artificial satellites?
Artificial satellites are man-made bodies that revolve around the earth. They are used for multiple purposes like communication, weather forecasting, remote sensing, etc. Examples: INSAT, IRS, SPUTNIK-I.
