Could the Star Ross 248 push earth out of its orbit?

So the force the Earth feels from Ross 248 is less than one trillionth of the force the Sun is using to currently hold the Earth in orbit. Ross would have to exert a force of over 3 trillion (3.1x10^12) times what it does in order to match the magnitude of the force exerted by the Sun. read more

” No. The Earth is held in its orbit by the force of gravity it feels from the sun. That force depends on the mass of the Sun, the mass of the Earth, and the distance between them. read more

Among the known stars, Proxima Centauri has been the closest star to the Sun for about 32,000 years and will be so for about another 33,000 years, after which the closest star to the Sun will be Ross 248.Proxima will make its closest approach to the Sun, coming within 3.11 light years of the latter, in approximately 26,700 years. read more

The orbit has the exoplanet and its parent star moving closer to us and in the blink of a cosmic eye (that’s 79,000 Earth years, technically), it will be our nearest stellar neighbor. That gives us time to speed up our rockets (and maybe invent Star Trek’s warp drive). Ross 128, again, is 11 light years away. read more
