Sonce/expanzija

wiki:

It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury and Venus, and render Earth uninhabitable in five billion years

The Sun gets its energy by crushing together hydrogen and other atoms until they fuse together. By Einstein’s famous equation E = mc2, this energy output leads to a loss in the Sun’s mass of over 350 billion tonnes each day.

Ker je gravitacija funkcija mase obeh teles in distance, ali do tedaj, do sončeve expanzije, merkur,venera,zemlja,... ne bodo odleteli ven iz trenutne orbite in nas ne bo scvrlo ?
