In astronomy, measuring helps us learn the size, distance, and brightness of things in space.
Without these measurements, it would be hard to compare stars, planets, and galaxies.
Astronomers can’t use rulers or scales like we do on Earth. Instead, they have other ways to measure objects in space.

Each type of measurement tells us something important:
- Distance: Knowing how far away something is helps us understand its size and energy.
- Angles: Measuring angles helps us find where objects are in the sky and how big they are.
- Brightness: Studying brightness shows us how much energy stars and galaxies give off.
Making these measurements helps us learn more about space and the Universe.
