The mass of the star Proxima Centauri is 12% of the mass of the sun. What would be the likely impact on the motion of Earth if the sun were replaced by Proxima Centauri? A day would be shorter because the gravity experienced by Earth would be stronger. A day would be shorter because the gravity experienced by Earth would be weaker. A year on Earth would be longer because Earth would move relatively faster in its orbit. A year on Earth would be longer because Earth would move relatively more slowly in its orbit.

Answer :

A year on Earth would be longer because Earth would move relatively more slowly in its orbit is the corrects answer have a nice day :)

The impact on Earth's motion if the sun is replaced by Proxima Centauri in a year on Earth would be longer due Earth would move relatively faster in its orbit.

What is an orbit?

The word 'orbit' makes reference to the movement of a celestial body around a star at a particular period of time.

  • Earth moves faster in its orbit because our planet spends a calendar year to complete an orbit.

In conclusion, the impact on Earth's motion if the sun is replaced by Proxima Centauri in a year on Earth would be longer due Earth would move relatively faster in its orbit.
