The background information of the natural satellite of earth the moon

The pioneering astronomer Galileo Galilei was the first to use a telescope to make scientific observations of the moon, describing in a rough, mountainous surface that was quite different from the popular beliefs of his day that the moon was smooth.

Temporary satellites[ edit ] On 14 Septemberan object estimated at 5 meters in diameter was discovered in near-polar orbit around Earth.

Moon Facts: Fun Information About the Earth's Moon

This means the Northern and Southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.

Older craters have rounded and subdued profiles, the result of continued bombardment. The rock, which measures about 6 cm 2. Because Earth and the moon are so similar in composition, researchers have concluded that the impact must have occurred about 95 million years after the formation of the solar system, give or take 32 million years.

Although similar to terrestrial basalts, lunar basalts have more iron and no minerals altered by water. Its multiring ramparts are characteristic of the largest basins; they are accented by the partial lava flooding of low regions between the rings. Night after night, the Moon seems to change its shape in the sky, turning from a thin crescent into a full circle.

The lunar landscape has not changed much in thousands of years.

The Moon, our own natural satellite

This siderophile depletion is an important clue to the history of the Earth-Moon system, as discussed in the section Origin and evolutionbelow. At full moon its system of bright radial rays is easily seen from Earth. In MayKeyhoe asserted that the search had been successful, and either one or two objects had been found.

It was claimed for the United States and a research base was established there by Swift Enterprises. How did the moon form? The Moon and Earth consequently exert a strong gravitational influence on each other, forming a system having distinct properties and behaviour of its own. The object was later identified with the lost artificial satellite SRA, or possibly its companion SRB, which were launched in and lost in When a body strikes a much larger one at speeds of many kilometres per second, the available kinetic energy is enough to completely melt, even partly vaporize, the impacting body along with a small portion of its target material.

For example, the moon always shows us the same face. This was followed hundreds of millions of years later by a second episode of heating—this time from internal radioactivity—which resulted in volcanic outpourings of lava.The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.

It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).Surface gravity: m/s² ( g).

The Moon, our own natural satellite The Moon is Earth’s only natural satellite. Our planet’s trusty companion is an airless, silent world without any signs of life.

Though a satellite of Earth, the moon, with a diameter of about 2, miles (3, kilometers), is bigger than Pluto. (Four other moons in our solar system are even bigger.) The moon is a bit more than one-fourth (27 percent) the size of Earth, a much smaller ratio () than any other planets and their moons.

Claimed moons of Earth

Earth Sun And Moon Facts The natural satellite of the earth, visible (chiefly at night) by reflected light from the sun; daydream: have dreamlike musings or fantasies while awake; "She looked out the window, daydreaming". Moon: Moon, any natural satellite orbiting another body.

In the solar system there are moons orbiting the planets. Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have 1, 2, 67, 62, 27, and 14 moons, respectively. Other bodies in the solar system, such as dwarf planets and asteroids, also have moons.

The moon was likely formed after a Mars-sized body collided with Earth. Earth's only natural satellite is simply called "the moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in
