Question

Planet A has a greater mean distance from the Sun than planet B. On the basis of this fact, which further comparison can be correctly made between the two planets?
1Planet A is larger.
2Planet A's revolution period is longer.
3Planet A's speed of rotation is greater.
4Planet A's day is longer.

The actual shape of Earth's orbit around the Sun is best described as _?
1a very eccentric ellipse
2a slightly eccentric ellipse
3an oblate sphere
4a perfect circle

Why does the angular diameter of the Sun, as seen from Earth, appear to be greater during our winter than summer?
1Earth is closer to the Sun during our winter.
2 Northern Hemisphere is inclined toward the Sun during our winter.
3The Sun expands during our winter.
4Earth is revolving around the Sun faster during our winter.

Terrestrial planets move more rapidly in their orbits than the Jovian planets because terrestrial planets are
rotating on a tilted axis
more dense
more massive
closer to sun

Answer 1

2
2
1
Closer

Answer 2

2 3 2

Answer 3

question 1: 2

question 2: 1

question 3: false, the angular diameter of the sun is not larger in winter than it is in summer, in fact in our summer the earth is further away from the sun than in winter so if anything it should be the other way around.

question 4: closer to the sun

Answer 4

Tim must be from Australia.

The answer to question 3 is that the Earth is closer to the sun during the *northern hemisphere* winter. I believe that perihelion is on January 4th (the day the Earth is closest to the sun).

Answer 5

Hello:

What an interesting group of questions...

Question Three: Answer number 2

Question Four: Answer : More dense...
The Jovian planets are called the Gas Giants and
are made up of vast amounts of hydrogen and helium,
with other gases of smaller amounts mixed in.
