The table shows properties of some planets in the solar system.

To determine on which planet a given object would weigh the most, we need to look at the surface gravity compared to Earth.

The surface gravity values compared to Earth are as follows:

• Venus: 0.90
• Earth: 1.0
• Mars: 0.38
• Jupiter: 2.53
• Saturn: 1.06
• Neptune: 1.14

Jupiter has the highest surface gravity at 2.53 times that of Earth. Therefore, an object would weigh the most on Jupiter.

So the correct response is: Jupiter.

Saturn

To determine which planet takes the longest to complete one revolution around the Sun, we can refer to the "Length of Year (Earth years)" property provided in the table. Here are the values:

• Venus: 0.62 years
• Earth: 1.0 years
• Mars: 1.9 years
• Jupiter: 11.9 years
• Saturn: 29.4 years
• Neptune: 164.8 years

Neptune takes the longest time to complete one revolution around the Sun, with a period of 164.8 Earth years.

Therefore, the correct response is: Neptune.

The planet Uranus is between Saturn and Neptune. What is a reasonable estimate for the distance, in AU, from Uranus to the sun?

To estimate the distance from Uranus to the Sun, we can look at the distances of Saturn and Neptune from the Sun, as given in the table:

• Saturn: 9.5 AU
• Neptune: 30 AU

Since Uranus is between Saturn and Neptune, a reasonable estimate for the distance from Uranus to the Sun would logically fall between these two values.

Taking the midpoint between 9.5 AU (Saturn) and 30 AU (Neptune) would yield an estimated distance of around 19.75 AU.

Given the response options provided:

• 32
• 4
• 20
• 8

The closest reasonable estimate in AU for the distance from Uranus to the Sun is 20 AU.

To determine which planet is most similar in size to Earth, we can refer to the "Size (compared to Earth)" property in the table. The values are:

• Venus: 0.94 (94% of Earth's size)
• Earth: 1.0 (reference size)
• Mars: 0.53 (53% of Earth's size)
• Jupiter: 11.0 (11 times the size of Earth)
• Saturn: 9.1 (9.1 times the size of Earth)
• Neptune: 3.9 (3.9 times the size of Earth)

From this comparison, Venus is the planet most similar in size to Earth, as it is 94% the size of Earth.

Therefore, the correct answer is: Venus.
