The Solar System
Grade 5 Science Worksheets
Our Solar System is one in billions of the planetary systems that orbit around a star. The Solar System is made up of a star, eight planets and countless smaller bodies like dwarf planets, asteroids, comets and meteoroids. It is estimated to have formed around 4.6 billion years ago when a giant interstellar molecular cloud collapsed under the influence of gravity.

Location of Solar System
A galaxy contains a large group of stars, gas, and dust bound together by gravity. The Milky Way is a large barred spiral galaxy that contains our Solar System in one of its four spiral arms. The Solar System goes around the center of the Milky Way every 250 million years. Our Solar System is about 25,000 light-years away from the center of this galaxy. The stars that we see at night belong to Milky Way.
Structure and Composition of the Solar System
The Solar System consists of the Sun and everything bound to it by its gravity- the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, the dwarf planets, several moons, asteroids, comets, and meteoroids.

SUN
Sun is the star present at the center of the solar system. Some of its characteristics are as follows-
- It constitutes 99.86% of the total mass of the solar system.
- Its diameter is 110 times wider than Earth’s.
- The sun’s atmosphere contains 74% hydrogen, 24% helium and rest include oxygen, carbon, nitrogen, neon, iron etc.
- The Sun generates huge amounts of energy by combining hydrogen into helium in a process known as Nuclear Fusion. This generates a temperature of 9941 degrees Fahrenheit on the surface, the core temperature being around 28 million degrees Fahrenheit. Thus we get heat and light from the Sun.
- It takes 8 minutes for light from the Sun to reach Earth.
Planets
A planet is an astronomical body moving in an elliptical orbit around a star. They are massive, rounded, and spherical in the structure under the influence of their own gravitational force. There are about 8 planets in our solar system. Earth is the only habitable planet known. These planets are divided into two categories:
- TERRESTRIALS: Planets like Mercury, Venus, Earth and Mars are terrestrials and are closer to the sun. They are primarily composed of rock and metal.
- GIANT PLANETS: They are massive planets and include Jupiter, Saturn, Uranus and Neptune. Jupiter and Saturn are the most massive and are known as gas giants. They are composed mainly of hydrogen and helium. Neptune and Uranus are called ice giants. They have icy cores and are composed of substances with high melting points like water, ammonia and methane.

Dwarf Planets
These are worlds that are too small to be considered full-fledged planets, but too large to fall under smaller categories. Astronomers estimate that there could be as many as 200 dwarf planets in the Solar System. The confirmed names are Ceres, Pluto, Eris, Haumea and Makemake. Pluto which was earlier considered a planet has been given the status of a dwarf planet now, but the controversy still exists. The following picture depicts their sizes as compared to Mercury.
Moons
Moons, also known as natural satellites orbit around planets and asteroids. There are around 205 known moons in our solar system. Most orbit the giant planets –Saturn and Jupiter, but even smaller worlds like Pluto have moons orbiting it. They come in various shapes and sizes with some of them having atmospheres and hidden oceans. They are mostly made of rocks and some are made of ice.
The Earth-Moon relationship is a special one. It makes our planet more livable by giving us stable climatic conditions. It takes 27.3 days to orbit around the Earth.

Some of the Moons around Jupiter
Asteroids
Also known as minor planets, an asteroid is a small chunk of rock or even metal left from the early formation of the Solar System. They tumble and spin as they orbit around the Sun. There are over 150 million asteroids in the Solar System and their size varies from few feet to hundreds of miles in diameter. They are mostly lumpy like potatoes. Most of them are found in the main asteroid belt between the orbits of Mars and Jupiter.
Comets
Described as ‘dirty snowballs’, comets are made up of frozen gases, rocks and dust left over during the formation of the Solar System. They usually orbit around the Sun in elongated paths. As the comet gets close to the Sun, some of the ice melts and boils along with particles of dust forming a giant glowing head with a trail of debris behind it made of dust and gases. Comet Halley is a famous comet visible to the naked eye every 75-76 years.
Meteoroids
Meteoroids are ‘small bodies’ of the Solar System. They are small chunks of matter that are approximately the size of a house to the size of tiny pebbles. They are fragments of asteroids and comets. When a meteoroid enters Earth’s atmosphere, it travels faster than a bullet and collides with particles in the air resulting in a luminous phenomenon known as a meteor or a shooting star.
All these objects orbit around the Sun in a direction in which the Sun rotates. They move in a counterclockwise direction when viewed from top. Besides them, there is an interplanetary medium made up of highly tenuous gases and dust that make up the Solar System.
