include Mercury‚ Venus‚ Earth‚ and Mars. On the other hand‚ the jovian planets are composed primarily of hydrogen and helium. They generally have low densities‚ rapid rotation‚ deep atmospheres‚ rings‚ and numerous satellites. These planets include Jupiter‚ Saturn‚ Uranus‚ and Neptune. The closest terrestrial planet to the sun is Mercury. Mercury is relatively small‚ and technically the eighth largest of all the planets. It is actually smaller in diameter than the moons Ganymede and Titan. Mercury

planets are Jupiter‚ Saturn‚ Uranus‚ and Neptune. 2. Size Comparison. How many Earths could fit inside Jupiter (assuming you could fill up all the volume)? How many Jupiters could fit inside the Sun? The equation for the volume of a sphere is Jupiter radius = 71492 km Earth radius = 6378 km 71492/6378= (11.21 km)3 = 1408.38 x 3.14 x 0.75 = 3318 About 3318 Earths could fit inside Jupiter Sun radius = 696000 km / 71492 km = (9.74 km)3 = 922.69 x 3.14 x 0.75 = 2174 About 2174 Jupiters could fit inside

Two space probes called Voyager 1 and Voyager 2 were launched in 1977. They went to Jupiter‚ Saturn‚ Uranus‚ and Neptune. They were launched in the United States from Cape Canaveral‚ Florida. It took two years to reach the first planet they were researching‚ Jupiter. Voyagers 1 and 2 took around 100‚000 pictures of the outer planets. They took pictures of Jupiter’s “swirling red atmosphere”‚ images of volcanoes on Jupiter’s moon‚ Io‚ erupting 200 miles into space‚ and awesome pictures of

as being the size of the smallest object to be called a planet. Mercury itself is less than half the size of Mars‚ and Mars is only about half the size of Earth or Venus. Earth and Venus are only about one-seventh the size of Jupiter. Why not pick one-tenth the size of Jupiter as the size of the smallest planet‚ if the cutoff is going to be chosen arbitrarily? In that case‚ Mars‚ Mercury and Pluto would all have to be classified as asteroids. If the size-cutoff between asteroids and planets is going

Mercury Mercury is called after the messenger of the Roman Gods. Mercury is 0.39 AU from the Sun. Mercury is 0.61 AU from the Earth. Mercury is quite a small planet. Its diameter‚ the distance right round its middle‚ is only 3‚031 miles or 4‚878 kilometres. Mercury’s average orbital speed is 48 km/s. Its orbit of the Sun lasts for only 87.96 days. Mercury only turns very slowly on its axis‚ taking 58.64 days to complete the turn from day to night. Mercury has an extremely thin atmosphere around

3.Galileo Galilei | Galileo Galilei was the first astronomer to use a telescope to study the heavens. Galileo made a number of observations that finally helped convince people that the Sun-centered solar system model (the heliocentric model)‚ as proposed by Copernicus‚ was correct. What is a Galilean telescope? The original design Galileo Galilei came up with in 1609 is commonly called a Galilean telescope. Galileo’s telescope with which Jupiter’s moons could be observed was made with a plano
