1: In this Book, we will cover The Earth, the Moon, and the Sun.
2: The Earth The earth is the third planet from the sun, the fifth largest and the densest from the Solar System.
3: The Earth is home for millions of species; matter of fact, it is the only place in Earth where life is known to exist. This planet appeared 4.54 billion years ago. | 71% of the Earth is covered with salt water oceans; the other 29% consists of continents and islands. | Did you know? Earth has a diameter of 12,760 km and mass of about 5.972 x 1024 kg
4: Structure of the Earth
6: The Moon | The Moon is Earth's only natural satellite and is the fifth largest satellite in the Solar System. It is the largest natural satellite in the Solar System relative to the size of its planet, a quarter the diameter of Earth and 1/81 its mass, and is the second densest satellite after Io.
7: Rotation of moon The same side of the Moon always faces the Earth. The Moon's rotation period is synchronous with its revolution period around the Earth. Size comparison The volume of the Earth's moon is the same as the volume of the Pacific Ocean. | Several mechanisms have been proposed for the Moon's formation 4.527 0.010 billion years ago, some 30–50 million years after the origin of the Solar System.
8: The Moon's Structure
9: GENERAL INFO: Moon Profile - Basic Lunar Information Name: Moon Age: 4.5 billion years old Mass: 73'490'000'000'000'000 million kg Shape: Egg-shaped Family: Member of our solar system, satellite of earth Active Relationships: Orbits around the earth Distance from earth: 384'467 km (~364 397 km at perigee, ~406 731 km at apogee) Traveling by car: Traveling by rocket: Traveling by light speed: 130 days 13 hours 1.52 sec Diameter: Driving around by car: 3476 km (1/4 of the Earth's) 4 days Gravity acceleration: 1.62m/sec2 (1/6 of Earth's) Revolution period: 27.3217 days Mean Synodic period (new moon to new moon): 29.530588861 days Mean orbital velocity: 1'023 km/sec
10: The Sun is a star in the Solar System. It has a diameter of 1,392,000 (which are about 109 Earths) The Sun is color white, even though it might appear yellow due to the Atmospheric Scattering. | The Sun has been active since 4.5 Billion years ago. Temperature: (15,000,000 C; 27,000,000 F) and pressure (340 billion times Earth's air pressure at sea level). | The Sun
11: The Sun has an expected life time of about 11 billion years. | It takes only 8 minutes for sunlight to travel from the sun to the earth, which also means, if you see the sun go out, it actually went out 8 minutes ago. | For 186 days you can not see the sun in the North Pole. | Because of the speed at which the sun moves, it is impossible for a solar eclipse to last more than 7 minutes and 58 seconds. | The Sun is just another of billions of stars out there. Despite its huge size, it is tiny: there are many other stars out there that are hundreds of times as large as the Sun. | The Sun makes up about 99.8% of the weight of our entire solar system. Its mass is about 2 x 1027 tonnes, and is more than 300,000 times heavier than the Earth. | Interesting facts about the Sun...
