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

You will need! - One empty 35mm plastic film canister and lid. These are getting harder to find, but stores that develop film should have some. (The white canisters work much better than the black ones do.) - One fizzing antacid tablet (such as Alka-Seltzer – Get this from your parents) - Water - Safety goggles What to do? Put on those safety goggles and head outside – no really, when this works, that film canister really flies! If you want to try the indoor version, do not turn the canister upside down in step 5.  Break the antacid tablet in half. Remove the lid from the film canister and put a teaspoon (5 ml) of water into the canister. Do the next 2 steps quickly Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.) Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 meters. About 10 seconds later, you will hear a POP! and the film canister will launch into the air!

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.
