Planet

Michael Jordan, a basketball player, is one of the most famous sportsmen on the planet.

Beyond the orbit of Neptune (the furthermost planet), it takes a long time to leave the Solar System.

Planet rovers are robots for exploring distant planets.

Because it takes a long time to send a radio signal from Earth to another planet, the robots do much of their work alone, without commands from Earth.

Mercury is the smallest and innermost planet in the Solar System.

Because Mercury was the fastest planet as it moved around the Sun, it is named after the Roman deity Mercury, the messenger of the gods.

And MESSENGER, launched in 2004, orbited Mercury over 4,000 times in four years before exhausting its fuel and crashing into the planet's surface on April 30, 2015.

Mercury is the most cratered planet in the Solar System.

Mars is the fourth planet from the Sun and the second smallest planet in the Solar System after Mercury.

Mars is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye.

Mars is a terrestrial planet with a thin atmosphere, having surface features like those of the impact craters of the Moon, and valleys, deserts, and polar ice caps of Earth.

They can last for months and cover the entire planet.

Jupiter is the largest and biggest planet in the Solar System with a diameter of 142,984 km.

It is the fifth planet from the Sun.

As the principal founder of Microsoft, Bill gates is one of the most influential and richest people on the planet.

Saturn is the sixth planet from the Sun in the Solar System.

It is the second largest planet in the Solar System, after Jupiter.

Saturn has 62 known moons orbiting the planet;53 are officially named.

The largest moon is Titan, which is larger in volume than the planet Mercury.

Saturn is the only planet in the Solar System that is less dense than water.

Venus is the second planet from the sun.

It is a terrestrial planet because it has a solid, rocky surface like other planets in the inner solar system.

Venus comes closer to the Earth than any other planet does.

Venus is sometimes called the sister planet of Earth as they are quite similar in size and gravity.

Venus was the first planet to have its motions plotted across the sky, as early as the second millennium BC and spins very slowly on its axis, it spins in the opposite direction to the other planets.

Venus is a terrestrial planet so, like the Earth, its surface is made of rock.

This makes the surface of Venus the hottest of any planet's surface in the Solar System with an estimated average temperature of 480 °C (896.0 °F).

Two higher areas called continents make up the north and south of the planet.

Neptune ,is the eighth and last planet from the Sun in the Solar System.

It is the fourth largest planet and third heaviest.

It also contains small amounts of methane which makes the planet appear blue.

Neptune also has the strongest winds of any planet in the solar system, measured as high as 2,100 km/h or 1,300 mph.

The planet was the first to be discovered by mathematical calculations instead of using a telescope.

Because of Uranus's odd movements in its orbit (the line which a planet follows in moving), it made astronomers search for the new planet.

The planet was visited by only one spacecraft, Voyager 2 on August 25, 1989.
