The Buck Moon – this name comes from Native American traditions. July is when male deer (bucks) begin to grow new antlers, symbolizing growth and regeneration – see Full Moon names and meaning.

So if you step outside that evening and find yourself marvelling at a moon that looks like it’s been super-sized at the low horizon ~ this’s called Moon illusion.

Earth at aphelion

Earth reaches aphelion ~ its farthest point from the Sun in its yearly orbit. At that moment, Earth will be about 94.5 million miles (or 152.1 million kilometres) from the Sun.
o
Despite being farther away, it’s still summer in the Northern Hemisphere – that’s because seasons are caused by Earth’s axial tilt, not its distance from the Sun.

You’ll likely see the Moon and Pleiades very close together in the early morning sky, low on the north-eastern horizon, but not a full occultation – still, it’s a beautiful sight – binoculars will better the view unexpectedly.
