Can something the size of the Earth also influence light and make it bend?
This artist's concept shows OGLE-2016-BLG-1195Lb, a planet discovered through a technique called microlensing.
General Relativity suggested that all light should travel in locally straight lines, but if space itself was being warped due to the presence of massive objects, then the direction a beam of light might find to be “straight” might not look so straight to an external observer.

In this image the light from a distant galaxy, nearly 10 billion light-years away, has been warped into a nearly 90-degree arc of light in the galaxy cluster RCS2 032727-132623.
The galaxy cluster lies 5 billion light-years away.
