# Can revolving movement also generate gravitational waves? [closed]

If an object revolves around a circular path at the speed of light could it still generate gravitational waves and what would be the simulation in inner area?

• If earth revolved around sun at the speed of light without self rotation would it still generate gravitation al waves? – NOob94 Jul 22 '16 at 7:13
• How do propose to make the Earth, or indeed anything else, rotate round the Sun at the speed of light? – John Rennie Jul 22 '16 at 7:18
• The revolution of two objects around each other will generate gravitational waves, just not very strong ones, unless the motion is relativistic. The gravitational wave emissions of Earth revolving around the sun have been estimated at 200W: en.wikipedia.org/wiki/Gravitational_wave. This is simply not measurable with any known technology. – CuriousOne Jul 22 '16 at 7:21

It doesn't need to go with around $c$. If it accelerates, it produces gravitational waves and if it is on a circular orbit, it accelerates. (With some exception: for example an (around it centre) rotating planet doesn't emit GW.)
