- The planets are arranged in a fixed order and orbit a central point - the Sun.
- Planets, depending where they are located in the solar system, have different physical properties.
- Each planet has its own unique characteristics.
- A planet's mass affects the gravitational pull.
- Some planets have rocky surfaces and some are made of gas.
- Some planets have a few moons, some have many and others have none.
- Our solar system is divided into two categories of planets, the major planets and the minor planets.
- The planets are not right next to each other. They are pretty far apart.
- Different planets have different types of atmospheres. Some planets have no atmosphere at all.

|
- The stars in the sky are VERY far away.
- A light year is a measurement of distance in space.
- Stars create heat by a process called fusion.
- The fusion process takes small atoms and makes them into bigger atoms.
- Stars are VERY hot compared to Earth.
- Stars have many layers and each layer has a different thickness and amount of heat.
- Stars make light.

| Constellations |
|
|
| |
|
- Constellations are patterns of stars in the sky.
- Before there was science and the tools of astronomy, people used to tell myths and stories to explain what they saw up in the sky.
- Constellations move across the sky, but they move because the Earth moves and rotates.
- Constellations move in the sky because of the tilt the Earth has on its Access.
- Constellations were created by people long ago and stories were attached to them to explain their shape.

| Telescopes |
|
|
| |
|
- Telescopes are one of the most important tools scientists have to study space.
- Big telescopes have similar structures to small telescopes.
- Big telescopes have huge mirrors that allow them to collect more light and see deeper into space.
- The eyepiece magnifies the image to make it appear closer.
- All the parts of the telescope have special jobs and work together to have people look out into space.
- Images collected by a big telescope are very different looking than images collected by a small telescope.
- Light travels a specific path through the telescope by being reflected off mirrors and bent through prisms.
