The best time for a venusian astronomer to look at Earth would be when our planet is opposite the Sun as seen from Venus, which last occurred in June 2020. This is called opposition. Amateur astronomers may remember the nice views we had of Mars’ surface features in October 2020, when the Red Planet was at oppositio
