The June solstice is this week. A Greek mathematician observed shadows during the solstice, had people make measurements, ran some calculations, and came up with the first known estimate of how big around the earth is.
Venus follows Mars in the space between Cancer and Leo in the evening sky. Saturn stays in Aquarius in the second half of the night. Jupiter's up at dawn.
