There are mainly two factors on the basis of which we can check the existence of the atmosphere on the surface of a planet. 1) Temperature present on the surface of a planet. We know that the temperature of a planet depends upon the ...

The strength by which a heavenly body reflects is called ALBEDO. It can be found by dividing the sun’s energy reflected by the incident energy on the planet. Clouds can be considered as the decent reflectors of light. Clouds play an important role in increasing ...

The two most common methods which are used to find the temperatures of the planets are discussed below: Wien’s Displacement Law: We know that planets emit radiations. Now, our work is to study the spectrum of the emitted radiations and their wavelength with respect to their ...

As we already know that the revolution of planets around sun is in egg shaped path. Also the planets revolve around their own axis which is passing through their centres. The rotation of the planet and time period of rotation of a planet can be ...

On the basis of observations it is said that the planet as well as its satellite rotate around a common centre of mass. Let O be the centre. So, both the planet and its satellite form a binary system. ...

Using the telescope if you will try to see any heavenly body such as moon, planet, etc then it will appear like a disc. Now we have to find the angle alpha made by the diameter of the planet at a point present on ...

There are large no of ways by which we can measure the distances of the heavenly bodies.Let’s find the distance of the planets from the earth’ surface. Let’s discuss the Parallax Method. a. Parallax Method: - Suppose a planet P is seen from the two distinct points ...

Sun’s family is known as solar system. The major objects that form the solar system are Comets, Meteors, Sun, satellites (or moons), nine planets and asteroids. We will discuss all the components in detail. Let us first discuss about the sun which is the major ...
