A human-operated spaceship reaches the moon in 3 days. The moon is about 386,400 km from Earth. Mars, our closest planetary neighbor, is, at its closest, about 140 times farther away from us than the moon if Mars stays in place. Assuming a very simple model of the solar system, about how long would it take that same spaceship to reach Mars?
A: About 22.5 years
B: About 2.5 years
C: About 1 year
D: About 7.5 years
What is the maximum possible distance that can be drawn between mars and Neptune…?
1) 630 cm
A human operated spaceship reaches the moon in 3 days…?
2) about 1 year
What is the main problem with this model if you were going to be used to study the dimensions of the solar system?
3) The planets are placed at the same distance from each other
Why do astronomers use astronomical units (AU) instead of kilometers (KM)
4) large distances are easier to express in AU then in KM
oh i found it! its about 1 year. so, this thread may end.
about 1 year is the answer!!
But how do I get the days?
DrBob222 you are not helping none of this helps
The answer is one year.
