The eclipse measurements of 1919, for example, which established that gravity bends light’s trajectory, have inspired a successful technique now used for finding distant planets.

Gas planets are not the only example of celestial bodies that resist diffusion due to gravity. Like gas planets, “stars are just giant balls of gas,” said Knittle. “And they hold together.” ...

That is, the destruction of distant stars or planets outside our solar system or galaxy would have an unnoticeable effect on earth. However, our sun is in close proximity to earth.
