Question

In the Heliocentric model _______ is at the center of the solar system.
A. Earth
B. Moon
C. Mars
D. Sun

Answer 1

Heliocentric model is an astronomical model that consists of planets, stars, sun, etc. in this model each of the planets will be located at a particular place and move in a particular direction. As we know that the sun is the universal light source and the earth is one of the planets that a galaxy consists of.

Complete step by step answer:
So the sun is an important part in the heliocentric model and even in the whole galaxy, where it consists of many planets and earth is one of it. Heliocentric model tells that all planets locate around the sun and revolve around it.
For suppose, the earth will revolve around itself that causes day and night for us and it also rotates around the sun that causes a completion of the year with 365 days or 366 days (leap year).
In the 3rd century it is found that the sun is the centre in the whole system and the planets will revolve around it.
Therefore, in heliocentric model the sun is at the centre of the solar system

So, the correct answer is “Option D”.

Note:
Here there will be another model called geocentrism, this model always says that the Earth is the centre of all the planets and even the sun located around it, please we should be careful about these two definitions and do not get confused. Where the heliocentric model will say that the sun is the centre of the whole system and the geocentric model says that the earth is the centre of the whole system.
