* 90,000 mph is incredibly fast. To put it in perspective, that's about 135 times the speed of sound.

* Spacecraft re-entry is extremely fast. Many spacecraft, like the Space Shuttle, would enter the atmosphere at speeds exceeding 90,000 mph.

* Meteors can be even faster. Some meteors, especially larger ones, can enter the atmosphere at speeds reaching 160,000 mph or even faster.

So, the answer is:

* Some spacecraft during re-entry

* Many meteors

It's important to note that these speeds are just the initial entry velocities. As objects move through the atmosphere, friction causes them to slow down considerably.
