Introduction In our solar system, nine planets circle around our Sun. The Sun sits in the middle while the planets travel in circular paths (called orbits) around it. These nine planets travel in the same direction (counter- clockwise looking down from the Sun's North Pole). The picture on the right shows the different paths and positions of each planet.
The Solar System is made out of two parts: The inner solar system contains Mercury, Venus, Earth and Mars. These four planets are closest to the sun. The outer solar system contains Jupiter, Saturn, Uranus, Neptune and Puto Each planet is named after God.
The inner planets separated from the outer planets by the Asteroid Belt.
In Class In class 4 we made a sentence in order of the planet this is the one I made My Very Elderly Mother Mercury Venus Earth Mars Just Severed Us nine Jupiter Saturn Uranus Neptune pizza’s. Pluto
Mercury is the closest to the sun but it’s not hot. Mercury orbits the sun once every days. Mercury is bright when Viewed from Earth, ranging from – 2.3 to 5.7 inches. The sun is only 28.3’c. Since Mercury is normally lost in the glare of the sun. Mercury can only be viewed in morning or evening twilight.
Venus is the 2 nd closest to the Sun Orbiting it every Earths day’s The planet is named after Venus, the roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset.
Earth Earth is the 3 rd planet near to the sun. Earth is a living planet. It’s age is 4.6 millions years old. It size is the 5 th largest planet in the solar system. Earth is White, green and blue The world is expected to continue supporting life for another 1.5 billion years
Mars Mars is red. Great dust storms came engulf the entire planet The effects of these storms are dramatic, including giant dunes, wind streaks, and wind-carved features. Scientists believe that 3.5 billion years ago, Mars experienced the largest known floods in the solar system.
Jupiter Jupiter is the 5 th closest to The sun. It’s the biggest planet. Where there’s a circle in the photo Its when they had the big storms And it is still going on now. It has 4 moons,.
Saturn Saturn is the 6 th planet near the sun. If you put all nine planets in a bucket of water only Saturn will float I think it is because it has loads Of rings. Saturn's ring system extends hundreds of thousands of kilometres from the planet.
Uranus Uranus is the 7 th planet near the the sun. The seventh planet from the Sun is so distant that it takes 84 years to complete one orbit. Uranus, with no Solid surface, is one of the gas giant planets (the others are Jupiter, Saturn, and Neptune). Uranus gets its blue-green color from methane gas. Sunlight is reflected from Uranus' cloud tops, which lie beneath a layer of methane gas.
Neptune Neptune is the 8 th planet near to the sun. After being ignored by French astronomers, Le Verrier sent his predictions to Johann Gottfried Galle at the Berlin Observatory, who found Neptune on his first night of searching in Seventeen days later, its largest moon, Triton, was also discovered.. Nearly 4.5 billion kilometres (2.8 billion miles) from the Sun, Neptune orbits the Sun once every 165 years.
Pluto is the 9 th planet near to the sun. It does not exist any more. Pluto tiny, cold and incredibly distant, Pluto was discovered in 1930 and long considered to be the ninth planet. People found out that it was a Dwarf planet.
Sun The sun is in the middle with all 9 planets orbiting the sun. The sun is a big star but is made out of a big ball of gas. The remainder consists of the planets (including Earth), asteroids, meteoroids, comets, and dust in orbit.
Moon The moon is bright. It comes in different phases as it travels around earth. The the Moon's surface area is less than a tenth of the Earth (about a quarter of Earth's land area). It takes 29 days to rotate around Earth. First man to land on the moon was an American astronaut Neil Arm Strong.
