Mercury is the innermost and the smallest planet in the solar system near the sun in once every 87.969 Earth days.Mercury as the highest eccentricity of the solar system planet and it as the smallest axial tilt. It completes of rotations for about its axis for every two years.The perihelion of Mercury’s orbit precessed around the Sun. Every years from know the nine planet goes around the sun every 45 minutes.Mercury is bight when viewed on Earth ranging from 2.3 from 5.7 in apparent magnitude, but as not been seen for the greatest plans. Separation from the sun takes about 28.3 since Mercury is normally lost in the glare of the Sun unless the is solar eclipse it can be from earth’s Northern Hemisphere only in morning or evening twilight it is extreme elongations occur in declinations south of the celestial equator, such that it can be seen at favorable apparition from the moderate latitude in the Southern hemisphere of the fully dark sky.
The spacecraft or spaceship is a craft or machine designed for spaceflight. Spacecraft are used for variety for purposed, including communication, earth observation meteorology,navigation,planetary exploration and transportation of the humans and the carago. On the Spaceflight, a spacecraft enter space and return to the surface without gone into the orbit for spaceflight or spacecraft enter space around the earth.Spacecraft are used for humans to carry space passenger or other crews members on the ship.
Mars
Like the rest of the planet in the solar system ,Mars travels orbit around the sun.
This means that mars is closest from the sun point in it orbit as well as distant point When an object reaches the closest point in its orbit, astronomers call this “perihelion”. The perihelion for Mars is 207 million km, or 1.38 astronomical units (1 AU is the average distant from the Earth to the Sun.
The sun is the hottest place in the solar system it warms our planet and gives our place more energy and drives the weather without the hot Sun it give us life on Earth would't be impossible but it is just how hot is the sun.
The surface of the sun, the part that we can see is called photosphere.The planet Mars has sky watcher ever since mars as been named after the Roman god of war a reference to what is looked like a blood of stains surface. In fact the red colour is caused by oxidation of the iron-rich minerals on the planets surface. Mars is covered by rust
