Our Solar system is 4.57 billion years old. Mercury and Venus are the only two planets in our solar system that have no moons. The Milky Way Galaxy 105,700 light years wide. The Hottest Planet in our solar system is Venus. There are 79 known moons orbiting Jupiter. If a star passes through close to a black hole, it can be torn apart. The Whirlpool galaxy (M51) was the first celestial object identified as being spiral. The sun makes a full rotation once every 25 to 35 days. NASA’s crater observation and sensing satellite (LCROSS) found evidence of water on the Earth’s moon. The Martian day is 24 hours 39 minutes and 35 seconds long. The sun weights about 330,000 times more that earth. Due to the sun and moon’s gravitational pull, we have tides because of lower gravity, a person who waits 220 labs on the earth would wait 84 labs on Mars. The highest mountain discovered in is the Olympus mons, which is located on Mars. Footprints left on the moon would not disappear as there is no wind. Space is completely silent. Nobody knows how many stars are in space. A full NASA space suit costs $12,000,000. Neutron stars can spin 600 times per second. There may be a planet made of diamonds. There is floating water in space. There is volcano on Mars three times the size of Everest. Spacecraft have visited all the known planets in our solar system. According to Mathematics, white wholes are possible, although as of yet we have found none. Uranus blue glow is due to the gases in its atmosphere. Together the sun and its planets are known as solar system.

The Earth:
Imagine you are an astronaut looking at the Earth from your spacecraft. What u see is a big blue ball covered with swirling clouds that hide features such as continents and mountains. The ball looks so blue because more than two- thirds of it is covered with water in the form of oceans, seas, lakes and rivers. The surface of the Earth, called the crust, moves all the time, but this movement is so slow we are not aware of it. Eventually, however, pressure builds up and causes earthquakes and volcanoes. Changes also happen when the crust is worn away by water or huge blocks of moving ice called glaciers.

Our planet can support life only because it gets light and heat from the sun. Without it, the Earth would be a cold, dark and dead place.

Read and be aware of our solar system.
