What Are Some Space Things That Have Straight-Forward Names?

One thing I love in astronomy is how some things’ names are so on-the-nose.


You have a large group of quasars? That’s a Large Quasar Group (LQG)

That LQG is particularly big? We call that the Huge Large Quasar Group.

We’re making a really big telescope? Let’s name it the Extremely Large Telescope (ELT)

Star made of neutrons? Neutron Star!

Star that pulses? Pulsar!

Really really massive black hole? Supermassive Black Hole!


I’m struggling to find adequate wording for Google, so I’m asking here. What are some other things in space that are simply just named what they are?
