How will you calculate the mass of a planet?
admin 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…
What is the direction and time period of the planets revolution about its own axis?
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.…
Explain the two different ways of finding the surface temperature of the planet?
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…

Explain the methods to check the existence of atmosphere on a planet?
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…
What is the chemical composition of the atmosphere present on the surface of a planet?
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…
What are the necessary conditions for the possibility of life on a planet?
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…
What is Sun?
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…
What is solar luminosity?
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…
What will be expression for the surface temperature of the sun?
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…
