White-tailed deer start growing antlers in March or April as the days start to lengthen. July marks the peak of their antler growth season, hence the name Buck Moon. Thunderstorms are also common in July, which is why it's also called the Thunder Moon.

Mercury is notoriously difficult to see from Earth, thanks to its proximity to the Sun. But on July 4, Mercury reaches its greatest eastern elongation, meaning the planet will be at its farthest apparent distance from the Sun in the evening sky. This event marks one of the best chances to see the elusive planet this year.

Pluto will reach its closest approach to Earth and align opposite the Sun on July 25, appearing slightly brighter (magnitude 14.4). This will be one of the best times to attempt spotting the dwarf planet, though a powerful telescope is required due to its faintness. Look in the constellation Sagittarius.
