How big of a neutron star would it take for the earth to make revolutions around such a tiny star???

Answer 1

seems you have no clue what you are talking about...
what do you mean by how big of a neutron star ??

Answer 2

Well, hows this, the average neutron star is only about 12 miles across, but has as much mass as about 1 1/2 of our Suns.

In order for the earth to revolve around a neutron star in an orbit similar to the one it has now, you would need a neutron star with the equivalent of 1 solar mass which means it would be somewhere around 10 miles across or so.

Hope that helps some.

Answer 3

well a neutron star can only be up to a certain size. they are very very tiny but they are extremely heavy, a teaspoonful of a neutron star weighs more than all of the vehicles in the world combined. so its not really the size of the star but they overall mass that dictates if the earth could make the same revolutions it does now, not sure how much it would have to be though

Answer 4

This question is a little ambiguous, however, a nuetron star is typically 25 miles + in diameter (smaller sizes increase the gravitation field to collapse to black hole, and then, who knows). Accordingly, the answer would depend on the mass of the revolving bodies and the distance between them - remember Newton's s Second Law!!
