To explain the puzzling phenomena astronomers in early times proposed a change in the simple geocentric model. This is called as epicycle model.
A small circle whose centre is on the circumference of a larger circle, in ptolemic astronomy.
It was seen as the basis of revolution of the seven plants, given a fixed central Earth.

As the Venus went around the epicycle, as shown in the diagram Venus would exhibit phases.
Also at times the planet would be nearer, making the apparent size grow bigger and at times far making the apparent size smaller.
If the Venus was going around the Sun, and its orbit is inside that of Earth, Venus would appear always near the Sun in the sky.
It can never be seen in the midnight sky. Two when it is near the Earth, it would be brighter and bigger compared to when it is on the other side of the Sun.
Thirdly only if the Venus is revolving around the Sun, it can exhibit gibbous phase, and the size of the gibbous phase smaller than the crescent phase.
If the Venus was revolving around the Earth, we can never see the gibbous phase of the Venus and it would be seen only if it is orbiting the Sun.

A constellation is a recognizable pattern of stars in the night sky when viewed from the Earth.
International Astronomical Union has classified 88 constellations to cover the entire celestial sphere.
Many of the old constellations have Greek or Latin names and are often named after mythological characters.
Ursa Major (Saptha Rishi Mandalam) is a large constellation and it covers a large part of the sky.
The most striking feature of this constellation is a group of seven bright stars known as big dipper (seven Sages in Indian astronomy).
Ursa Minor in Lattin means ‘the little bear’ it lies in the northern sky.
The Pole star – Polaris (Dhrua) lies within this constellation.
The main group, ‘little dipper’, consists of seven stars and is quite similar to that found in Ursa Major.

I would like to support Neelan, because Life is possible only on the Earth due to presence of water, oxygen, various gases and suitable temperature, which enables us to live.
Mala opposed Neelan’s view based on the following points :
Like the Sun, there might be billions of other stars with their own planets revolving around them.
Thus there are many chances of any planet getting the suitable conditions for supporting life.
