if a planet or another object orbits our sun at the speed of light would we be able to see it?

Answer 1

Einstien's theory predicts that an object travelling at the speed of light has infinite mass -so it can't happen . Even so, it would not be orbitting because at that speed it would not maintain an orbit of any shape - if it was passing through our solar system at a speed approaching the speed of light then its gravitational force ( it would be extremely massive due to the velocity) would cause severe disruption to the orbits of all the planets - so we would sense it even if we didn't see it.

Answer 2

yes, just like the stars it would be a light source. as you are declaring an orbit we would "see" it on the curve of the orbit.
Keep in mind that light takes a few seconds to reach the earth due to the distance the stars do not look like they are moving, however something in orbit around our sun would look like a blurry comet it would be moving so fast and easier to see as it comes around from the far side of the sun being the furthest point away from our vision.

Answer 3

Since the speed of light far exceeds solar escape velocity, there could be nothing orbitting the sun at that speed.

Answer 4

Of course we would see it, provided it emitted or reflected light. At any point in time it would be in a particular position, and the light emittied at that point in time, once it reached the viewer would be seen, the same as any other object. I would suggest that it's movement would not seem linear as it would appear to be moving slower as it moves closer to you.

The question of it being possible for an object to move at the speed of light in the first place is of course another question all together... for another day.

Answer 5

The Cosmic Microwave historic past grants an absolute common of relax with know to the Universe as an entire. in case you degree the Cosmic Microwave historic past, and this is (on established) isotropic, then you definitely're at relax interior the "Hubble pass". In particular Relativity, velocities do no longer merely upload. guy or woman A is traveling at a hundred and sixty,000 km/s guy or woman B is traveling at a hundred and sixty,000 km/s interior the choice path If guy or woman A measures the value of guy or woman B (as an occasion by Doppler shift with a radar gun), guy or woman A will degree a speed rather under the value of sunshine: 248020 km/s. this is merely the way Relativity works. this is experimentally examined.

Answer 6

No, because, at the speed of light, it would have infinite mass, light would not escape it, so it would be like a black hole. We would, however, be able to see a halo around it, namely an event horizon, where matter is dragged into it, giving off some energy as it does so.
Realistically, if if was in our solar system, it would attract and destroy all other matter around it, due to its infinite mass.

Answer 7

If it was emitting enough light like say Venus, then you would see it as a set of ripples, distorting space time. A bit like a pond that has a stone thrown into the middle of it!.

Answer 8

Yes it will leave a white ring in it's orbit ..we wont see the planet .but we will see the space distortion

Answer 9

According to Einstein's theory of relativity nothing (other than light) can travel at the speed of light.

Answer 10

of course NOT. think that your monitor is now refreshing with a rate of i donno, 7 times/sec, and you can't see this. How about a thing that is "refreshing" 300.000 times/sec? :)) i think i've done a horribile math here, but anyway, i was trying to give an example...so, no, the answer is no, you could not see an object that is moving with the speed of light.
