THIS IS ACTUALLY ASTRONOMY 1. Uranus is much larger than the Earth. If the Earth were a bouncy ball then Uranus would be a softball. IF Uranus has a radius of 25,360 km but has a day equal to 0.72 Earth days, what is its rotational speed?
9000 km
2. In some ways, Venus is Earth's twin. It is a rocky planet with similar size, mass, and gravity. However, some things
about Venus are dramatically different.
If Venus has a radius of 6,050 km but a rotational speed of only 6.52 km/h, how many Earth days does Venus need for a
complete rotation?
3. On the other hand, Venus is 108 million kilometers from the sun. If its speed of revolution is 125,600 km/h, how many
Earth days does it take to go around the sun?
I
4. Little Mercury is also a terrestrial planet and is the closest to the sun at about 58,000,000 km away. If Mercury goes
around the sun in 88 Earth days, what is its orbital speed in kilometers per hour?
5. a) Dark, cold, and stormy Neptune is the farthest planet from the sun (sorty Pluto). If Neptune takes 165 Earth years
to complete one trip around the sun, what is its orbital speed?
20 000
if anyone can help me that would be great it’s due today i don’t get this at all... you need to do some kinda formula
