At what phase of the Moon will the number of meteors whose direction of motion to the Earth is close to or coincide with the position of the Moon in the sky (that is, move “from the side” of the Moon) be the largest? How does the number of such meteors depend on the phase of the satellite?
1) (the main reason for the different number of meteors depending on the phase of the moon is indicated)
Relative to the north pole of the ecliptic, the Earth moves around the Sun counterclockwise. The main number of meteors is observed in the direction of the Earth’s motion in outer space – on the forward side of the Earth in the course of its orbital motion, on which more particles fall.
Based on these two positions, consider the main phases of the moon:
2) (correct answer with explanation in the last quarter)
The last quarter: the Earth is moving in its orbit “towards” the Moon: the number of meteors is maximum, since the number and speed of movement of meteoric particles is greatest – due to the direction of the Earth’s motion.
3) (correct answer with explanation in the first quarter)
First quarter: the number of meteors is minimal (opposite reason).
4) (correct answer with explanation on the full moon and new moon)
Full moon and new moon (intermediate cases): in general, the number of meteors should be statistically equal. But on a full moon, the moon is on the night side of the Earth, and on a new moon – on the day side, so it is almost impossible to see meteors on a new moon.
