It would be appreciated if we are notified at least one week in advance.DIRECTIONS AND PARKING Directions and information about parking can be found here.This continues for June and July before Mars appears to move in the original direction again beginning in August.The solution to the problem of retrograde motion is to realize that the Earth is moving more quickly around the Sun than Mars.However, because even in its most complex form it still produced errors in its predictions of the positions of the planets in the sky, some astronomers continued to search for a better model.

Each arrow is labeled with the date on Earth, and as both planets orbit the Sun, we see that the position of Mars with respect to the stars appears to move as time goes forward.In May of 2016, the Earth overtakes Mars, so the arrow for this date appears to move in the opposite direction compared to the previous dates.We have also measured the rotational period of the star to be 3.3 days and detected a number of flares consistent with a low-activity, middle-aged, late M dwarf. acknowledges support from NASA grant NNX13AF62G and National Science Foundation grant AST-1615315.
