Planet Distance from sun (in km) Distance in scientific notation
Mercury 57,909,000 5.7909*10^7
Venus 108,200,000 1.082*10^8
Earth 149,600,000 1.496*10^8
Mars 227,940,000 2.2794*10^8
Jupiter 778,400,000 7.784*10^8
Saturn 1,423,600,000 1.4236*10^9
Uranus 2,867,000,000 2.867*10^9
Neptune 4,488,400,000 4.4884*10^9
(dont know about pluto but Im putting it either way)
Pluto 5,909,600,000 5.9096*10^9 Answer the following questions using the data you have found. Show your work on all questions as indicated.

If a spacecraft was parked on Venus and needed to make a flight to Jupiter, how far would it need to travel? (Assume both planets are aligned with the sun and are on the same side of the sun.) Show your work and provide your answer in scientific notation.
Venus = 108,200,000
Jupiter = 778,400,000
778,400,000 - 108,200,000 = 670,200,000
The space craft would need to travel 6.702*10^8

Mercury, Venus, and Earth are the three planets closest to the sun. Would their combined distance from the sun be greater or less than the distance from the sun to Neptune? Show your work and justify your answer.
Mercury 57,909,000 +
Venus 108,200,000 +
Earth 149,600,000 =
Total 315,709,000
Neptune 4,488,400,000

The combined distance would be less than the distance from the sun to Neptune.

If Earth was 10 times farther away from the sun than it is now, which planet would it be closest to? (Assume all the planets are aligned with the sun and are on the same side of the sun.) Compare Earth's new distance to that planet. How far apart in scientific notation? Show your work.
Original Distance = 149,600,000
New Distance = 1,496,000,000,000,000,000
It would be closer to Dwarf Planet Pluto.
Earth ND: 1,496,000,000,000,000,000
Pluto : 5,909,600,000 . = Earth - Pluto = 1.49599999429*10^17
The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to reach Saturn from Earth. (Assume both planets are aligned with the sun and are on the same side of the sun.) Show your work. Convert your answer into scientific notation if necessary.
Earth: 149,600,000
Saturn: 1,423,600,000
Saturn - Earth = 1,274,000,000
1,274,000,000 / 28,000 = 45,500 H
It will take 45,500 hours for the shuttle to go from Earth to Saturn
