Nat (unit)
A nat is a unit that is used to measure the brightness of stars. Think of a star as a little light bulb in the night sky. Nat is like a ruler we use to measure how bright that light bulb is.
So if a star has a brightness of 1 nat, it means it's not very bright, like a small night-light in a dark room. But if a star has a brightness of 5 nats, it means it's really bright, like a big, bright flashlight shining in your face.
Scientists use this unit to compare the brightness of different stars and study how they behave. It's like comparing how bright different light bulbs are at home, but instead of using watts or lumens, we use nats to measure the brightness of stars in the sky!
