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?
