Jupiter

        Facts about Jupiter


Jupiter is covered in clouds Jupiter is the 5th planet from the sun
Jupiter’s giant red spot is a raging storm Jupiter is the biggest planet
in the solar system It is a giant spinning storm, resembling a hurricane
the storm is about 3 1/2 times the diameter of Earth Jupiter is a gas
planet.
Its ring is mostly comprised of dust particles from some of Jupiter’s
moons during impacts from comets and asteroids. The ring system
begins about 92,000 km above Jupiter’s clouds and reaches more
than 225,000 km from the planet
The largest of Jupiter’s moons, Ganymede is the largest moon in the
solar system. The moons are sometimes called Jovian satellites the
and the largest of them are Ganymede , Callisto , Io and Europe.
Jupiter has a very strong magnetic field. This is around 14 times
stronger than the magnetic field found on Earth , the largest of any
planet in the solar system.
Jupiter is the fourth brightest object in our solar system. After the Sun,
the Moon and Venus, Jupiter is the brightest and is one of five planets
which can be seen by naked eye from Earth.

Mars

         Facts about Mars
Mars is sometimes called the red planet because of the brownish-red colour of
its surface. Mars is the second smallest planet in the solar system behind Mercury.
Mars is the fourth planet from the Sun and last of the terrestrial planets and is around
227,940,000 km from the Sun.


The planet is named after Mars, the Roman god of war. It was known to the ancient
Greeks as Ares, their god of war. This is thought to be because of the red colour of the
planet which was also used by other ancient cultures. Chinese astronomers call Mars
the fire star while ancient called it Her Desher meaning the red one.
The tallest mountain known in the solar system is on Mars. Olympus Mons is a 21 km
high and 600 km diameter shield volcano that was formed billions of years ago.
Scientists have found a lot of recent evidence of volcanic lava which suggests Olympus
Mons may still be active.
It is the second highest mountain in the entire solar system, topped only by the Rheasilvia
central peak on the asteroid Vesta, which is 22 km high. When Mars is closest to the
Sun in its orbit the southern hemisphere points toward the Sun and this causes a very
short but fiercely hot summer.
Mars is the only other planet besides Earth that has polar ice caps. The northern cap
is called the Plenum Boreum, with Plenum Australe in the south. Water ice has also
been found under the Martian ice caps.

Earth


           Facts about Earth

Earth was formed somewhere around 4.54 billion years ago and is currently the only known planet to support lifes. ancient astronomers believed that the Earth was static and had other celestial bodies travelling in circular orbits around it.

They believed this because of the apparent movement on the Sun and planets in relation to their viewpoint. In 1543, Copernicus published his Sun-centered model of the Solar System which put the Sun at the centre of our solar system.

Earth is the only planet not named for a mythological god or goddess. The other seven planets in the solar system were named after Roman gods or goddesses.
For the five visible to the naked eye, Mercury , Venus , Mars , Jupiter and Saturn they all were named during ancient times. This Roman method was also used after the discovery of Uranus and Neptune. The word Earth comes from the Old English word Ertha meaning ground or land.
The gravity between the Earth and the Moon causes the tides on Earth. This effect on the Moon means it is tidally locked to Earth its rotation period is the same as its orbit time so it always presents the same face to Earth.Image result for earth
