Fortunately, the asteroid, named Sar2667, is just 1-meter wide, which means it poses no danger to Earth. by Remote_Combination14

Reply to comment by BloodBaneBoneBreaker in In the absence of cosmic radiation, would an object placed in space eventually cool to absolute zero? by IHatrMakingUsernames
Would there be anything for it to heat up? Would it loose energy from black body radiation with the energy traveling away as light in infrared? Will objects give off BBR all the way to 0k?

What about going into the void between galaxies and waiting (long time) until the expansion of space between the next closes object is greater than the speed of light. At that point any light (EMR) aimed in this direction would never reach it.

Current plan is for a robot to grab it, but they have not yet decided on what type of robot.

If the rock that hit it was destroyed to the point it can't reencounter Webb, then that is one less bullet in the revolver.

There was a super nova in human history that was bright enough to cast a shadow on a moonless night. I believe it lasted for a few days.
So if one is between stars and was lucky enough to have one go off, would have some level of illumination, but maybe very faint.

I read the books before the movie. I felt that the movie aged up the characters too much for how the book was. If the books are read with the thought that the characters are as old as they look in the movie than some of the behavior and how they do stuff won't fit.

Reply to comment by SomethingIrreverent in I want to see the Andromeda Galaxy with my naked eye. I can't, I have a method of finding it using Cassiopeia and a field to walk out on to get away from the lights. by vnevner
I have to do something similar with the Pleiades. Looking directly at it I see one dim star, but when I look off to the side and move my eye back and forth, I see a weird tiny cluster of dots.
Still am unable to see it well enough to count. Probably needs to be viewed form somewhere even further away from the cities.
