Notes on Planets
Mercury
It’s the nearest planet to the sun and is also the smallest planet in the solar system and takes around 88 days to complete one revolution (to be exact 88.97 days) which is the smallest time duration.
Venus
When observed from the Earth, it’s the second brightest (after the observed moon) and takes 224.7 Earth days to complete one revolution and 243 Earth days for rotation on its axis (it takes the maximum time period among all planets to complete one rotation). It rotates in the opposite direction to all planets except Uranus (from West to East).
Earth
It’s the third planet from the Sun and is the only known planet to harbor life. The Earth age is around 4.5 billion years old. It takes 365.264 days to complete one revolution around the Sun and 24 hours to complete one rotation on its axis (and after every four complete revolutions 4years it takes a day longer 366 days to complete a revolution). It is covered by 71% of water and its crust is divided into different tectonic plates (lithosphere). Earth’s innermost part remains active and its inner core is solid while the outer core is liquid which generates Earth's magnetic field.
Mars
It’s the fourth planet from the sun and also the second-smallest in the solar system. Its red color also makes it known as the red planet (presence of iron oxide). It has two moons - Phobos and Deimos. Its gravity is 38% of the Earth's gravity and takes 687 Earth's day and one full Mars year (16,500 hours).
Jupiter
It’s the fifth planet from the Sun and the largest planet among all. It’s also one of the brightest things that can be seen in the sky with the naked eye.
Jupiter is a giant ball of gases with one-thousandth mass of the Sun and lacks a well-defined surface.
Saturn
It’s the sixth planet from the Sun and the second-largest planet among the solar system. It’s a giant gas planet with an average radius which is nine times the radius of the earth The inner core is made of iron and nickel. An electric current within the hydrogen layer gives rise to the magnetic field of the Saturn which is a little less than the earth's magnetic field.
Uranus
It’s the seventh planet from the Sun and has the fourth-largest planet by mass and third-largest by radius. It's also referred to as ice giants and its primary component is similar to Jupiter and Saturn but it also has more ices such as methane, water, and ammonia and also traces of hydrocarbons. It rotates in the opposite direction from all the planets except venus( it rotates from west to east).
Neptune
It’s the eighth planet from the Sun. It’s the fourth-largest planet by diameter. The third most massive planet and is the densest giant planet - it’s slightly larger than Uranus and Neptune. It orbits the Sun every 164.8 years and is denser than Uranus and physically smaller than Uranus.
