What are the different types of satellites explain?
There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. 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.
What are the four main types of satellites?
Satellites: Types of Orbit
- Low Earth Orbit (LEO)
- Geosynchronous Earth Orbit (GEO)
- Medium Earth Orbit (MEO)
- Elliptical.
What are the major types of satellites?
There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar Satellite.
What is the difference between polar and geostationary satellites?
While polar orbits have an inclination of about 90 degrees to the equator, geostationary orbits match the rotation of the Earth. A sun-synchronous orbit passes by any given point with the same local solar time, which is useful for consistent lighting and sun angle.
How many different satellites are there?
According to Union of Concerned Scientists (UCS), which keeps a record of the operational satellites, there are 6,542 satellites, out of which 3,372 satellites are active and 3,170 satellites are inactive, as recorded by 1st January, 2021.
How many types of satellites are there in India?

What is a satellite class 6?
Satellites are celestial bodies that move around planets in the same way planets move around the Sun. They are made up of solid materials and gases. They do not have their own light. For example, the Earth is a planet. For example, the Moon is a natural satellite of the Earth.
What is difference between Sun-synchronous orbit and geosynchronous orbit?
➨Sun synchronous orbit is located at the altitude of 700 to 800 Km. Geosynchronous orbit is located at altitude of 35786 Km. ➨Orbital period of sun synchronous satellite is about 100 minutes. Geosynchronous orbit period is one sidereal day which is about 23 hours, 56 minutes, and 4 seconds.
How many satellite are there in the world?
There are nearly 6,542 satellites orbiting the Earth as of January 1, 2021. Out of which 3,372 satellites are active, and 3,170 satellites are inactive.
What are the different types of orbits and satellites?
There are many factors that decide which orbit would be best for a satellite to use, depending on what the satellite is designed to achieve.
- Geostationary orbit (GEO)
- Low Earth orbit (LEO)
- Medium Earth orbit (MEO)
- Polar orbit and Sun-synchronous orbit (SSO)
- Transfer orbits and geostationary transfer orbit (GTO)
What is a satellite class 7?
Any celestial body revolving around another celestial body is called its satellite. Earth is a satellite because it moves around the sun. The moon is a satellite because it moves around Earth.
What is a satellite for Class 5?
(Grades 5-8) series. 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.
What is the difference between polar and geostationary satellite?
Polar satellite revolves around the poles. The difference between the Polar Satellites and Geostationary Satellites are as follows: 1. Polar satellite revolves around the poles or in the north-south direction around the earth but geostationary satellite revolves in the direction of the earth or east-west direction.
