Seasonal Constellations
Recognise named constellations visible in different seasons and understand why we see different constellations at different times of year — because Earth’s orbit around the Sun changes which part of the sky we face at night
What a learner can do afterwards
- Name at least three constellations (e.g. Orion, Ursa Major/Big Dipper, Leo, Cassiopeia)
- State that different constellations are visible in different seasons
- Explain that this happens because Earth's orbit means we face different directions in space at different times of year
The lesson
You already know how to spot Orion and the Big Dipper, and you know Earth spins and circles the Sun. Now put those two ideas together. As Earth travels along its orbit, your night side points toward a different direction in space each season. That means the stars behind you change too, and so do the constellations you can see.
In January, Mia looks up after dinner and finds Orion, with his three-star belt. By June, Orion is gone. Instead she finds Leo rising in the east. Same sky, same Earth, but six months later Earth sits on the other side of the Sun, so night now faces a different direction.
A few constellations, like the Big Dipper, stay visible most of the year because they circle close to the pole. Others, like Orion, only show up for part of the year. Check the season to know which one to look for.
Because Earth orbits the Sun, we face a different part of space each season, so different constellations rise into view: Orion in winter, Leo in spring, and others through the year.
