Venus


 Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon. Named after the Roman goddess of love and beauty, Venus is the second largest terrestrial planet.

1.Size
    Venus is nearly as big as the Earth with a diameter of 12,104 km. Venus having 81.5% of the Earth’s mass. Both also have a central core, a molten mantle and a crust. Therefore,Venus is often called the Earth’s sister planet.
2.Hottest Planet
    The dense atmosphere of around 96.5 percent carbon dioxide traps heat and causes a greenhouse effect,therefore the average surface temperature is 462 °C,even Venus does not tilt on its axis, there is no seasonal variation
3.Brightest Planet
    The brightest object in the sky after sun and Moon is not a star but a planet which is Venus.Therefore Venus is sometimes referred to as the “morning star” and “evening star”
4. Day and year
It takes 243 Earth days to rotate once on its axis.The orbit of the planet takes 225 Earth-days – making a year on Venus shorter on day on Venus
                                 " One day on Venus is longer than one year"
5.Clockwise Rotation
     Most other planets rotate counter-clockwise on their axis, however Venus, like Uranus, rotates clockwise. This is known as a retrograde rotation and may have been caused by a collision with an asteroid or other object which caused the planet to change its rotational path.
6. Sulpuric acid cloud
    The dense clouds of sulpuric acid are present in the atmosphere which make it impossible to view its surface from outside its atmosphere.
7. Atmospheric Pressure
   Atmospheric pressure on Venus is 92 times greater than the Earth’s.The pressure felt by a human on the surface would be equivalent to that experienced deep beneath the sea on Earth.

Mercury    Mercury is the closest planet to the Sun.Mercury is one of four terrestrial planets in the Solar System, and is a rocky body like Earth. It is the smallest planet in the Solar System 1. Size    It has the diameter of 4,879 km which make it "smallest" planet of solar system. 2. Mass    It has mass of   3.30 x 10^23 kg (5.5% of Earth).Therefore, it has only 38% of gravity as compared to earth.                      3. Second Hottest Planet    Instead of closest planet to sun, it is not the hottest planet, because it has no atmosphere(because of weak gravity) to regulate the temperature, therefore it has large variation in temperature during night(-170 degree Celsius) and day(430 degree Celsius). 4. Day and Year    A year in Mercury is 88 days, yet a Mercury day is 176 Earth days. 5.Second Densest Planet     After the Earth, Mercury...

Saturn Saturn is the sixth planet from the Sun. It is best known for its fabulous ring system .It is the second largest planet in our solar system .  Like Jupiter, it is also a gas giant and is composed of similar gasses including hydrogen, helium and methane. Some amazing facts About Saturn: 1.Visible to naked Eye    It is the fifth brightest object(after Sun,Moon,Venus and Jupiter) in the solar system and is also easily studied through binoculars or a small telescope.                                    2.Year and Day    Saturn spins on its axis very fast. A day on Saturn is 10 hours and 14 minutes, whereas Saturn goes around the Sun very slowly. A year on Saturn is more than 29 Earth years.                                 3.Rings   Saturn is best known for ...

Jupiter Jupiter is the largest in the   Solar System  and fifth planet from the Sun. It is a gas giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Some amazing facts About Jupiter: 1.Visible to naked Eye    Jupiter is the fourth brightest object in the solar system. Only the Sun, Moon and Venus are brighter. It is one of five planets visible to the naked eye from Earth.                                            2.S hortest Day   Jupiter turns on its axis once every 9 hours and 55 minutes. It has the shortest day of all the planets.                             3. Year    Due to the large distance of Jupiter from sun, it orbits the Sun once every 11.9 Earth year...
