Mercury, being in the greatest eastern elongation, entered simultaneously in conjunction with Mars and Jupiter. What planetary configurations can be observed at this moment from Mercury?
Since Mercury is in the greatest eastern elongation, then the angle with the apex in the center of Mercury between the directions to the Sun and the Earth is 90 ° (see figure). If we conduct observations from Mercury, then the Earth will be in western quadrature. Mars and Jupiter will be in the opposite direction, that is, in the eastern quadrature, while simultaneously joining each other.
