  2. What is a Planet? -A Planet is a Celestial body that is in orbit around the Sun -Has enough mass so it’s own Gravity pulls into a near-round shape (Spheroid) -Is Gravitationally dominant in it’s own orbit -There are Eight Planets in the Solar System Definition of a Dwarf Planet: -It orbits the Sun -Has enough Gravity so can turn into a Spheroid shape -Is not Gravitationally dominant in it’s own orbit -Is not a Moon

  3. Mercury • Mercury is the planet nearest the sun • It has a diameter of 3,032 miles (4,879 kilometers), about two-fifths of Earth's diameter • Mercury orbits the sun at an average distance of about 36 million miles (58 million kilometers) • Scans of Mercury made by Earth-based radar show that craters at Mercury's poles contain water ice • The floors of the craters are permanently shielded from sunlight, so the temperature never gets hot enough to melt the ice • The temperature on Mercury can range from 450 degrees °C to -176 degrees °C • Mercury has an atmosphere! Mercury is surrounded by an extremely small layer of helium, hydrogen, oxygen, and sodium! * Mercury can’t sustain life because: it gets constantly bombarded with solar wind, gets too much radiation and of course, it’s too hot.

  4. Venus • The diameter of Venus is about 7,520 miles (12,100 kilometers), approximately 400 miles (644 kilometers) smaller than that of the Earth • The surface of Venus is extremely hot and dry. There is no liquid water on the planet's surface because the high temperature would cause any liquid to boil away • Thick clouds of sulfuric acid cover Venus • The temperature on Venus is almost always somewhere around 465 degrees°C *Venus can’t sustain life because the surface is covered with volcanoes, it rains sulphuric acid and it’s the hottest planet in the solar system.

  5. Earth • Earth has a diameter of about 8,000 miles (13,000 kilometers) • Earth is about 93 million miles (150 million kilometers) from the sun • Earth is the Planet we live on • It is the only Planet (as far as we know) can sustain life *So far, Earth is the only planet that can sustain life.

  6. Mars • Viewed from Earth, Mars is a bright reddish-orange •  It owes its color to iron-rich minerals in its soil. This color is also similar to the color of rust, which is composed of iron and oxygen. • It’s colour comes from the Iron-Oxide or rust in it’s soil • Mars is 141,620,000 miles (one hundred forty-one million, six hundred twenty thousand) • (227,920,000 kilometers) from the Sun • Mars is 6,792km (4,220 miles) in Diameter • The temperature on Mars can be 27 degrees°C to -129 degrees°C *Mars may have been able to sustain life, but today it is a barren, desert world. Mars can’t sustain life because it doesn’t have a strong magnetic field so the solar wind will evaporate any water on the surface, and it is very cold.

  7. Jupiter • Jupiter has a diameter of 88,846 miles (142,984 kilometers) • Jupiter is mostly made out of Hydrogen, Helium and Nitrogen • Basically it’s a big ball of gas • The temperature at the top of Jupiter's clouds is about -230 degrees F (-145 degrees C). • Measurements made by ground instruments and spacecraft show that Jupiter's temperature increases with depth below the clouds • The temperature reaches 70 degrees F (21 degrees C) • The diameter of Jupiter is 142 984 kilometers *Jupiter can’t sustain life because it does not have a surface so if you stood on it you would fall away to the core and there you would melt because the temperature is 30,000°C

  8. Saturn • Saturn has seven thin, flat rings around it • Saturn’s distance from the sun varies from about 941,070,000 miles (nine hundred forty-one million, seventy thousand) at its farthest point to about 840,440,000 miles (1,352,550,000 kilometers) at its closest point • The temperature at the top of Saturn's clouds is about -285 degrees F (-175 degrees C) • The diameter of Saturn is about 120 536 kilometers • If you were to put Saturn in a Bathtub, it would float! Saturn can’t sustain life because it doesn’t have a solid surface. And it’s too cold.

  9. Uranus • It’s distance from the sun is 1,784,860,000 miles (one billion, seven hundred eighty-four million) • Uranus’s diameter is 51 118 kilometers • Max. Temperature: -200°C • Min. Temperature: -214°C • Uranus has rings just like all the other outer Planets Uranus can’t sustain life because it doesn’t have a solid surface. And it’s too cold.

  10. Neptune • The blue clouds on Neptune are mostly frozen methane • Neptune’s diameter is 30,775 miles (49,528 kilometers) • Neptune’s distance from the Sun is  279,310,000,0 miles (two billion, seven hundred ninety-three million, one hundred thousand) • Min. Temperature: -218 degrees Celsius • Max. Temperature:-200 degrees Celsius Neptune can’t sustain life because it doesn’t have a solid surface. Also it is too cold.
