If Earth were 10 times farther from the sun than it is currently, it would be closest to Uranus.
To calculate the new distance between Earth and Uranus, we first need to determine Earth's current average distance from the sun. The average distance between Earth and the sun is approximately 149.6 million kilometers (km) or 1.496 x 10^8 km.
If Earth was 10 times farther away, its new distance from the sun would be 10 x 149.6 million km = 1.496 billion km or 1.496 x 10^9 km.
The average distance between Uranus and the sun is approximately 2.88 billion km or 2.88 x 10^9 km.
Therefore, Earth and Uranus would be approximately 2.88 billion km - 1.496 billion km = 1.384 billion km apart.
In scientific notation, this would be 1.384 x 10^9 km apart.
If Earth were 10 times farther from the sun than 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. About how far apart would they be in standard notation and in km? How far apart in scientific notation in km? Show your work.

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 (1,443,500,000 km) from Earth (149,600,000 km). (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.
To determine the time it would take for the space shuttle to reach Saturn from Earth, we can use the formula distance = speed × time.
The distance between Earth and Saturn is 1,443,500,000 km, and the speed of the space shuttle is 28,000 km per hour.
To find the time it takes to travel this distance, we can rearrange the formula: time = distance / speed.
Plugging in the values, we have:
time = 1,443,500,000 km / 28,000 km per hour = 51,482.1429 hours.
Rounding to the nearest hour, it would take approximately 51,482 hours for the space shuttle to reach Saturn.
Converting this to scientific notation: 5.1482 x 10^4 hours.
