was any missions sent inorder to study about it?

what are the nine planets in the solar system Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. what features does the third one have? It is the third planet from the Sun and the only astronomical object known to harbor life. how was it formed? UNANSWERABLE what shape does it have? The shape of Earth is nearly spherical. how does it's surface look like? Nearly 75% of the continental surfaces are covered by sedimentary rocks, although they form about 5% of the crust. The third form of rock material found on Earth is metamorphic rock, which is created from the transformation of pre-existing rock types through high pressures, high temperatures, or both. how fast does it rotate the sun? Earth's rotation period relative to the precessing or moving mean March equinox (when the Sun is at 90° on the equator), is of mean solar time (UT1) . Thus the sidereal day is shorter than the stellar day by about 8.4 ms. does it have a moon? Yes what is it's speciality? It may have dramatically affected the development of life by moderating the planet's climate.

During the Devonian period, for example, (approximately ) there were 400 days in a year, with each day lasting 21.8 hours. The Moon may have dramatically affected the development of life by moderating the planet's climate. Paleontological evidence and computer simulations show that Earth's axial tilt is stabilized by tidal interactions with the Moon. Some theorists think that without this stabilization against the torques applied by the Sun and planets to Earth's equatorial bulge, the rotational axis might be chaotically unstable, exhibiting chaotic changes over millions of years, as appears to be the case for Mars.
