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…
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…
The composition of a planet can be checked from the radiations of the spectrum. Large number of dark lines can be found in a spectrum. From these dark lines we…
There are three basic conditions for the existence of life on a planet 1. Water on the planet should be in abundance. 2. The planet’s atmosphere must be free from…
The brightest star near to earth is called sun. The emission of electromagnetic radiations in radio as well as visible regions is done by sun. Its other name is ‘Yellow…
Amount of energy scattered by sun per second in all directions is called as solar luminosity of the sun. Its symbol is Ls. Let’s suppose that there is a hollow…
Let’s suppose that the temperature on the surface of sun is T and radius R. Also suppose that the sun is a black body and is present at the centre…
Let’s take into account a planet revolving around the sun having mass m and T is its period of revolution. Suppose mass of sun to be M and R its…
Sun spots are the dark spots which are present on the visible disk when the snaps of sun are taken in the presence of white light. These black spots have…
According to the rule of nature that nothing is permanent. So, stars after completing their life period become dead ultimately. Stellar evolution basically describes the life cycle of a star.…
