Jupiter and Venus
Jupiter is the fifth planet from the Sun and is the most massive planet in our solar system. It has an equatorial diameter of 143,000 kilometers. It is 11.2 times the size of earth and has a mass 318 times the size of Earths. You could also fit almost 1400 Venus's inside Jupiter. Jupiter has an enormous magnetic field, has 63 moons, and it also has rings which form a miniature solar system of its own. Jupiter is made primarily of the gasses hydrogen and helium which makes Jupiter's atmosphere similar to the suns, "it is a big ball of gas". Jupiter rotates west to east and its rotation is so fast that it bulges out at its equator and it takes 11.85 years to orbit once around the sun. One day on Jupiter compared to that of Earths lasts just 9.9 hours. where as a day on Venus lasts 243 days. Jupiter is usually the second brightest planet we can see and it can often be seen all night.
Venus is the second planet from the Sun and is 12,103 kilometers across. Almost the same size as Earth. Venus rotates east to west and it rotates so slowly that it cannot create a magnetic field. It is made of rock and metal and its atmosphere contains mostly carbon dioxide. Venus’s atmosphere is so rapidly spinning that it creates a scorching hot temperature, hot enough to melt lead and has a surface pressure 90 times that of Earth. Venus does not have any moons or rings like that of Jupiter. Venus rotates backwards from the rest of the planets. It takes 224.7 days to orbit the sun and one day on Venus lasts 243 days. Venus is also the brightest planet in the sky.
