Astronomy for backyard stargazers
I've started stargazing from my backyard. Teach me the constellations, the planets, the Moon's phases, what binoculars and small telescopes can show, and the science behind what I'm looking at.
What you'll learn

- 1
Why Humans Watch the Sky
- Recognize astronomy as the study of objects and events beyond Earth.
- Understand why people have observed the sky for timekeeping, navigation, calendars, and curiosity.
- See backyard stargazing as part of a long human tradition.
- 2
The Sky as a Daily and Yearly Clock
- Understand that Earth’s rotation causes the daily motion of the sky.

- Recognize the horizon, zenith, and cardinal directions.
- Understand simple ways to orient yourself outdoors at night.
- 4
Constellations and Star Patterns
- Understand what a constellation is and how it differs from an asterism.
- Recognize that constellations are pattern tools, not groups of nearby stars.
- Become familiar with a few major beginner constellations and easy star patterns.
- 5
The Moon: Our Closest Celestial Neighbor

- 7
The Planets in the Night Sky
- Recognize planets as worlds that orbit the Sun.
- Distinguish planets from stars by their appearance and motion.
- Become familiar with the most commonly observed naked-eye planets.
- 8
The Solar System as a Family of Worlds

- Understand the broad difference between rocky inner planets and giant outer planets.
- Recognize smaller Solar System bodies such as dwarf planets, asteroids, and comets.
- 9
Stars: What They Are and Why They Shine
- Understand that stars are hot balls of gas producing light and heat.
- Recognize the Sun as a star.
- Learn simple visible differences among stars such as brightness and color.
- 10
Deep-Sky Objects Beyond the Stars You Can Name
- Recognize the main kinds of deep-sky objects beginners hear about.
