[Physics] Does gravity have 'elasticity'? If a solid sun-sized object zooms across space at the speed of light, then abruptly stops, does it take gravity some time to 'settle' around it?

Gravity is "emitted" by an object with mass. So to use what might be a better example, if a massive object popped into existence at a particular place, it would start "emitting" gravity waves from that time. Another object one light-minute away would start feeling its gravity about a minute after it appeared.
