Are there any instruments monitoring space objects (meteors) that might hit our sun or any other plant?

We know that we got scientists monitoring space for meteors that might collide with earth. But what about objects hitting the sun or any other planet in our solar system. Any significant meteor hitting one of these planets or the sun might cause an imbalance that would still have an effect on life on earth. Any feedback out there??

What we do when we see a meteor with a decently large mass, is we take its coordinates and we plug them in to find out its path. So when we determine whether or not a meteor will hit Earth, we are also determining if it will hit any other planet or the sun itself.
Reply:No, there are no instruments to the best of my knowledge. There will also be no significant imbalance if a meteor were to hit one of the planets. Eg the impact of comet Shoemaker-Levy on Jupiter had no effects.
Reply:There is a spacecraft called SOHO which monitors activity on the Sun. It has detected numerous comets falling into the Sun since it was launched several years ago. The Sun is so hot the comets actually evaporate before reaching the Sun's phosphere. It is also so large that you could drop an object the size of Earth into the Sun, and it wouldn't even hiccup.


Comet Shoemaker-Levy 9 (so named because it was the ninth comet jointly discovered by Eugene Shoemaker and David Levy) fell into Jupiter. The net effect, other than one less comet, was that Jupiter showed some black splotches for a couple weeks.


It is possible that in the year 1187 some monks at an English monestary actually saw the effects of a meteor striking the Moon, creating a crater now named Joliot-Curie. From their reports, a cloud of dust large enough to see on Earth was ejected, and remained visible for close to an hour.


Frankly, even if a new crater the size of Hellas Basin (Mars), Caloris Basin (Mercury), or Valhalla (Callisto) (all run close to 1300 miles across) were formed, there would be no effect on Earth, unless it hit here, in which case we would come close to sterilizing the planet. Oh, some meteors resulting from splash might ultimately reach us. BFD
Reply:Almost anything could hit the Sun and it would be of no consequence. The Sun is really big and even planets hitting it wouldn't affect it. Most things would burn up before getting there anyway.
Reply:The SOHO space craft has seen several comets hit the Sun. See the source. Also, Jupiter was hit by a comet in the 1990s, and every astronomer in the world was watching. But the answer to your question is no. Nobody really cares about other planets or the Sun getting hit. That could not cause any imbalance in the solar system at all. The impacts are just too small to make any difference. They only reason it is a big deal on Earth is all those delicate life forms we have here that would be killed by something that is a nothing little bump to the planet as a whole.
