Our solar system has a central star the sun. It is a monster; in fact it makes up 98% of the matter in our solar system. The gravity created by the large body exerts itself on the 8 planets that rotate around it in orbits. The solar system is thought to have formed 4.6 billion years ago. The closer a planet is to the sun, the hotter the average surface temperature on that planet. Each planet has a bit of personality itself. The solar system also has piles of rocks floating around in the form of meteoroids. There are also a little bit of sparkle going on across the solar system in the form of comets.

You will find a lot of work on planets, the sun and our moon (Luna). As the sheets progress we look at space exploration.

Moon Phases 1

As the moon orbits around the Earth, we see a different side of the moon. As shown in the diagram below, sometimes we see the lit side and sometimes the dark side.

Phases of the Moon 2

Provide the names for the phases drawn in the 8 boxes below using the names listed in the following table.

Da Planets

Provide the names for the planets shown in the diagram below using the names listed in the following table.

The "inner planets" are those closer to the sun than the solar system's asteroid belt. Provide the names for the inner planets shown in the diagram below using the names listed in the following table.

Outer Planets

The "outer planets" are those farther from the sun than the solar system's asteroid belt.

Exploring the Solar System

Although many objects such as asteroids, comets, and meteors orbit our solar system's sun, the largest objects travelling around the sun are the planets.

Planets Puzzle

Use what you have learned about the planets of our solar system to complete the puzzle. You may need to refer to science book or an encyclopedia.

Sun Anatomy

The sun is the star nearest to the Earth. Provide the names for the parts of the sun shown in the diagram below using the names listed in the following table.

Comet Anatomy

Comets are objects that travel through space and are made of a combination of dust and ice. They are sometimes called "dirty snowballs" because of this.

Asteroid Belt

Between Mars and Jupiter is a large belt of rocks called asteroids orbiting the Sun. These asteroids may be pieces of a planet that broke apart millions of years ago.
