Planet: Mars 1: - Mars is red because its soil is very oxidized (iron oxide). 2: - The brightest stars in the night sky are not really stars, but the planets Jupiter, Venus, Mars and Mercury. 3: - The Martian dust storms that occur every two or four years on Mars are so powerful that they can cover the entire planet with dust for months. 4: - The Martian "day" is only a little longer than a day on Earth. On Mars, one day lasts 24 hours, 37 minutes, 23 seconds, while on Earth, one day lasts 23 hours 56 minutes, 04 seconds. 5: - Scientists have gathered many evidences that suggest that Mars was once significantly more habitable than it is today, but scientists are still far from responding if there were ever living organisms on Mars or not. 6: - Mars is rich in water ice, in fact, NASA in 2007 stated that the volume of water ice in the ice cap of the South Pole, if it melted, would be enough to cover the entire planetary surface at a depth of 11 m

Planet: Jupiter 1: - Jupiter's moon, Ganymede, is the largest moon in our solar system, larger than the planet Mercury, and is the first known moon that has its own magnetic field. 2: - The Sun contains more than 99.8 percent of the total material (mass) in our solar system, while Jupiter contains most of the rest. 3: - Jupiter rotates in less than 10 hours, which means that the planet's surface moves at almost 50,000 km / h. 4: - Comet Shoemaker-Levy 9 crashed into Jupiter in July 1994, with the biggest accident ever seen. 5: - When Jupiter was formed it was much hotter and twice the size it is now, it continues to decrease at a speed of 2 centimeters per year due to heat radiation. 6: - Jupiter's core is not metallic, but due to the immense pressure inside Jupiter, the core has become a metal. This metal is liquid metallic hydrogen. 7: Jupiter has 2.5 times the mass of all the other planets in the solar system combined, and it would ta

If you are having problems remembering the planets in their correct order, just remember this sentence:-  " My very educated mother just served us nine pickles ," Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto (now a 'dwarf-planet', not a planet anymore).

Pluto.  1: - The Sun looks 1600 times weaker from Pluto than from Earth. 2: - One year in Pluto is equal to 248 Earth years. 3: - Pluto has not finished an orbit since it was discovered in 1930, taking 248 years to go around the Sun. 4: - About 20 years ago, Pluto's moon, Charon, was discovered. 5: - A day on the planet Pluto is approximately the duration of a week on Earth. 6: - Sunlight takes 8 minutes to reach Earth, 12 minutes and 47 seconds to reach Mars, and 5.5 hours to reach Pluto. 7: - Until 2006 Pluto was considered one of the planets of our solar system, but since 2006 it is classified in a new category called "dwarf planets". 8: Pluto was discovered in 1930 by astronomer Clyde Tombaugh. 9: While it may seem obvious what a planet is, the definition has become more complex since 2006 when the International Astronomical Union voted to reduce Pluto's status (discovered in 1930 and considered a planet since then) to a

Our Solar System. Big, small but round. But, why all the planets and stars are round?  The eight planets in our solar system differ in many ways. They are of different sizes. They are different distances from the sun. Some are small and rocky, and others are large and gaseous. But all are nice and round. Why is that? Why don't they have cubes, pyramids or discs? Planets are round because of a process known as "spherical shape formation". This process is caused by the forces of gravity and centrifugal force. Gravity is the force that pulls all objects towards the center of mass. The stronger the gravity, the more compact an object will be. As a planet forms, the gravity of all the matter within it causes it to pull together and become denser. This results in the planet becoming more and more spherical in shape. Additionally, as a planet spins on its axis, the centrifugal force caused by this rotation also contributes to the spherical shape.

Within the Solar System, the average temperature on: • Pluto is around -235°C, • Neptune around -220°C, • Uranus -210°C, • Saturn -184°C, • Jupiter -153°C. • The temperature on Mars varies between about -87°C and -5°C, with an average of around -46°C. • The lowest natural temperature on Earth (recorded at Vostok, Antarctica in 1983) is -89°C; the highest surface temperature on Earth (recorded at Al 'Aziziyah, Libya in 1922) is 58°C; the mean overall temperature on Earth is 14°C. Planet Biography. Planets Surface Temperatures. Why temperatures differs from planets to planets? In general, the surface temperature decreases as the distance from the sun increases. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface above the lead's melting point of 880 ° F (471 ° C).

Planet: Saturn 1: - Saturn's rings are only a few hundred million years old. 2: - The Spitzer infrared telescope recently discovered another ring around Saturn. 3: - The rings of Saturn are formed by bright particles of water ice. 4: - But, the new Saturn ring is composed of dark dust particles, not water ice, and extends from 8,000,000 miles to 12,000,000 miles from the center. 5: - The planet Saturn has a lower density than water. Then, if placed in water it would float. 6: - The moon Titan of Saturn has hundreds of times more oil and natural gas than all known reserves on Earth. 7: - Saturn is not only the planet with rings, Neptune also has its own ring system.

Sun 1: - The Sun was approximately 10 times brighter than it is today, after forming from its interstellar gas cloud. 2: - The Sun produces so much energy, that every second the nucleus releases the equivalent of 100 billion nuclear bombs. 3: - The strongest color light emitted by the sun is green, but we see the combination of all the colors of the sun as white light. 4: - The average temperature on the surface of the Sun is 6,000 ° C. The brown dwarf star CFBDSIR 1458 10b is not hotter than a cup of coffee. 5: - The center of the Sun is about 27 million degrees Fahrenheit (15 million ° C). 6: - Our Sun can be gigantic but it still loses 360 million tons of materials every day. 7: - Every second, the Sun pumps more than one million tons of materials into space through the solar wind (electrically charged particles). 8: - The Sun takes about 220 million years to make a revolution of the Milky Way. 9: - If the Sun became a Black Hole, it would
