I think this is a pretty fun exercise for people to understand basic points of relativity in general (pardon the pun), and how Lorenz transformations work.
The objects floating around exist in a different 4 dimensional reference frame than we do. ?Similar to Captain Scott Kelly's recent year in space and his description of age. ?Note that his year in space at 28,000 km/sec resulted in about 8 milliseconds of time dilation. ?apply that over 4 billion years.
(8 mS / year) X 4 billion years = 32,000,000 seconds = 8888 hours = 370 days... ?

If Captain Kelly had remained in orbit for 4 billion years, he would be about 1 year older than his sibling.

It's true meteors travel at an insignificant percentage of the speed of light. Speeds up to 260,000 kilometers an hour are reached by meteors entering the earth's atmosphere versus light's maximum of 1079252848.8 kilometers an hour in a perfect vacuum.

Outer space is very, very cold and is an imperfect vacuum. If it has any mass, the speed of light can be much slower. In an extreme situation, perhaps a velocity where the comparative speed of the meteor would be in the 5% range. Which would have a measurable affect on its age as a meteorite.

I mention this, because published papers establish that the colder the mass through which light is being perceived, the slower its speed. For instance, the speed of light through very cold, laser-bathed, sodium atoms, can be only 50 meters a second!
