As seen from an American location.
Venus is exaggerated 150 times in size, to show its crescent shape. The arrow through it shows its movement (against the starry background) from 2 days earlier to 2 days later. The Moon is exaggerated 4 times in size.
The antapex of Earth’s way (marked with my red steering-wheel symbol) is the direction away from which we are traveling at this time in our orbit. You can see that the Moon appeared near that position when it was at first quarter on Aug. 20 about 3 Universal Time, crossing outward over Earth’s orbit behind us.
