Will the Earth eventually crash into the sun?
Earth Is Spiraling Away From The Sun For Now, But Will Eventually Crash Into It. … Eventually, the Earth will lose its orbital energy and spiral into the Sun, even in the event that the Sun doesn’t engulf the Earth in its red giant phase.

Will Earth ever lose gravity?
Gravity would soar as the entire planet is pulled into the hole. … Over the next few billion years, Earth’s gravity will change by tiny amounts because of several events.
