Plasti-scene How do we know there are 9 or 8 planets in our solar system and whaat do we know about them.

Facts the sun is a star. there is a black hole at the centre of the galaxy. A gas cloud in space is called a nebula. light can not escape from a black hole An escape velocity is the speed an object needs to be moving break free from the gravital pull of a planet, star or black hole. the black hole has an escape velocity faster than the speed of light. .

Below mars.



When the first probes went to mars ther revealed mars as a baren planet bet later on new probes found water ice beneath the surface an if the first robot that went to mars might have found ice if it had dug 10 centimetres deeper. Some people think the first person to go to mars is alive today, could it be you? Mars is red because the rocks on mars have rusted. Mars has two moons. Mars used to have water on it. On Mars there is a canyon that was carved by water which is about as wide as Australia. It takes 6 months to go to Mars in a rocket and the total trip to mars and back takes about 3 years. Mars has almost twice the amount of gravity than the moon so it is very hard to land on even for robots. Vehicles are being desighned to be used on mars to transport astronauts or cosmonauts depending on who lands on mars first. Once every year there is a giant global dust storm that block the veiw of sattelites that are watching mars. There is a volcano on mars that is 27 kilometers tall. Martians if they exist the would more likeley be bacteria than little green men with lasers. The Atacarma desert is a lot like mars and bacteria still live there so it is possible that there is life on mars. We might be from mars and the organisms we evolved from could have gone to earth on a meteorite. Microbes can prodoce methane and there is methane on mars. 6 men stayed in a warehouse for 6 months to try to find out about what it would be like to travel to mars. If people find life on mars it would prove that in the universe life is commen.

Jupiter is a planet that is full of gas and has a storm on it called the red spot that is bigger than the earth. Jupiter has a moon called europa. Europa is covered in ice that may have water undeneath. because there is water on europa people think that there might be life on europa. Recently scientists have found out that jupiter is missing 1 of it's cloud belts. Jupiter is made out of gas and cannot be detected by radio telescopes. Jupiter is the largest planet in our solar system. Jupiter has 63 moons. Jupiter is som big you could fit every planet in th solar system onto it. Jupiter spins so fast it bulges and it's days only lasts 10 hours. Jupiter has rings like saturn tough you can't se them as easily. jupiters moon ganimead is the largest moon in the sola system. Ganimead ha it's own magneticfield.



Saturn is a planet that is well known for its rings. saturn is a gas giant. A gas giant is a large planet that is mainly made up of gas. the temperature of saturn is about -178 degreese celcius. Saturns rings are made up of ice particles. One of Saturns moons called titan is so cold that the groung is ice and the rivers are liquid methane (fart gas). Saturn is the scond biggest planet in the solar system. Saturn is a very hot planet. Saturns rings are no thicker than a two story building. Saturn has 62 moons. Saturns ringsare 300000 kilometres wide. Saturn is stormy just Like Jupiter. The winds on saturn can blow at speeds around 900 miles an hour. The winds on Saturnare sronger than they are on jupiter. Saturn creates more heat tha it recieves from the sun. Saturns moon enceldes is a place where scientists think they might find life and enceledes is the hottest place in the solar system that people have tried to find life on. Scientists think that there might be life on enceledes because there are huge geises on the south pole and on earth bacteria live near geisers. Some scientists think that saturns C ring is made from ice blasted from the geisers on enceledes.
