Terrestrial

The first for planets nearest the sun are known as terrestrial planets because of their Earth like characteristics especially their Rocky composition. But each of the four terrestrial planets Mercury, Venus, Earth and Mars has distinctive features that set it apart from its neighbours in the solar system.

Mercury, closest planet to the sun, orbits the sun in only 88 Earth days but it revolves on its Axis so slowly that one mercurian day lasts 59 Earth days. It has a large iron suggesting that it lost most of its surface in an ancient collision full stop Mercury appears to be shrinking still has its iron ore grows cold.

Earth has a unique blue and white appearance because more than 70% of its surface is covered with water and its atmosphere is filled with cloud rich in oxygen fullstop both its optimum distance from the sun and the presence of water in three states liquid solid and vapour make Earth conductive to life. Earths Terrain vary from that of any planet and its life forms thrive on land and in water.

Mars’s iron rich soil gives it a reddish glow. Half the size of Earth Mars is known for the oversized feature of its Terrain. Its Valles Marineris canyon stretches from 2500 miles, equivalent to the distance from los Angeles to New York city. Its Olympus mons volcano stands at least 15 miles high more than twice the height of the the Mount Everest. Despite Mars’s inhospitable atmosphere, the United States still hopes to send a manned spacecraft to test Earth closest neighbour

Ceres, a dwarf planet resides in the Atal asteroid belt that orbits the sun between Mars and Jupiter fullstop about one-fourth the size of the earth’s moon, Ceres is the largest object in that belt of solar system leftovers.

What is the asteroid belt?

The asteroid belt located between the orbits of Mars and Jupiter is a wide belt of material orbiting the sun that contains perhaps millions of asteroid. There is an asteroid recently upgraded to a job planet is also found here a full stop these asteroids are spread over such a large Swath of space that a spacecraft travelling through the twelfth would really encounter 1. They tend to collect in orbiting expectorated from one another by significant gaps called Kirkwood gaps, which are caused by the gravitational pull of Jupiter. Jupiter’s gravity occasionally poles an asteroid out of orbit and sends it hurtling to the sun. A real asteroid veers out of the belt and rockets to earth.

What does an asteroid look like?

The image to the right was created from a composite of four photographs of asteroid 433 also known as Eros coma in our solar system’s asteroid belt. The photographs were taken by The Near Earth Asteroid Renders (NEAR) was mission in February 2000. The NEAR spacecraft entered Eros’s orbit about 200 miles from the asteroid and about 160,000,000 miles from Earth. A year later the NEAR spacecraft landed on Eros and confirm that it is without atmosphere or water.

This asteroid is heavily created suggesting that it is relative Li old. The large creta visible hair measures about 4 miles across. A its depression can be seen in a Boulder, equivalent in size to a single family house.
