Skywatching Events in July 2025

Earth at Aphelion – 3 July

At around 19:54 UTC on 3 July, Earth will reach aphelion — the point in its orbit where it is farthest from the Sun. Despite the extra distance of about 152.1 million kilometres, this has little effect on our temperatures. Seasons are driven more by Earth’s axial tilt than by our proximity to the Sun.

Mercury at Greatest Elongation East – 4 July

Mercury reaches its greatest elongation east on 4 July, meaning it will be at its farthest distance from the Sun in the evening sky. This is a great opportunity to spot the tiny, elusive planet after sunset. Look towards the western horizon shortly after dusk for the best view. Use an interactive sky map or binoculars for help if conditions are challenging.

Full Buck Moon – 10 July

The Full Moon on 10 July peaks at 20:36 UTC and is known as the Buck Moon. This name comes from the time of year when male deer, or bucks, begin growing their new antlers. Expect a brilliant, bright Moon to dominate the night sky, perfect for casual moongazingor moonlit photography.

New Moon – 24 July

The New Moon occurs at 19:11 UTC on 24 July, offering the darkest skies of the month. With no Moon to wash out the sky, this is the perfect time for stargazing, spotting deep-sky objects, and viewing the Milky Way stretching overhead.

So grab your telescope or binoculars, or simply step outside — July’s night sky has wonders waiting for you!
