When does an eclipse season occur?
only if both the sun and the moon appear at nodes of the moon's orbit
any time the sun appears at a node of the moon's orbit
only once every 18 years
any time the moon appears at a node of its orbit
Homework Answers
According to the given problem,
Answer: only if both the sun and the moon appear at nodes of the moon's orbit
Reason: An eclipse season is the only time during which the Sun (from the perspective of the Earth) is close enough to one of the Moon's nodes to allow for an eclipse to occur
The lunar nodes are 2 points where the plane of the Moon's orbital path around Earth meets Earth's orbital plane around the Sun, the ecliptic. The orbital paths meet because the plane of the Moon's path around Earth is inclined at an angle of approximately 5° to the ecliptic.

a) For a solar eclipse to occur, the Moon must be located between the Earth and the Sun. However, both the Earth’s and the Moon’s orbits are not circles but ellipses. The distance between the Earth and the Moon varies between 357,000 and 407,000 km. The distance between the Earth and the Sun varies between 147.1 × 106 and 152.1 × 106 km. Calculate the range of solid angles under which the Moon and the Sun can appear, and decide...

69. Solar Eclipse on Earth The sun has a Sun diameter of about 865,000 mi with a maxi- mum distance from Earth's surface of about Moon Earth 94,500,000 mi. The moon has a smaller diam- eter of 2159 mi. For a total solar eclipse to occur, the moon must pass between Earth and NOT TO SCALE Umbra the sun. The moon must also be close enough to Earth for the moon's umbra (shadow) to reach the surface of Earth. (Source:...

se 4: Phases of the Moon Everyone has seen the Moon, which is a natural satellite that orbits the Earth. As the Moon rotates around the Earth it is exposed to various amounts of light from the Sun. The reason for this is simple, the Moon at night because it is reflecting light produced by the Sun and because the Earth is slightly out of the direct line of sight between the Moon and Sun. If it were not, a...

1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...

Today, the Moon’s orbit around
Earth has a semi-major axis of a=384,400 km and an orbital period
of 27.32166 days.
a. The Moon slowly moves outward due to tidal braking of the
Earth’s rotation, and at some future date the Moon will have an
orbital period of 47 days. Compute the semi-major axis of the
Moon’s orbit at this future date (express your answer in
kilometers).
semi-major axis = 5.5*10^5 km
b. Today, the Moon has an angular diameter of...
