Exciting Astronomical Events to Observe in July 2025

As July unfolds, astronomy enthusiasts can look forward to a series of captivating celestial events and opportunities to deepen their understanding of the cosmos. From the Earth reaching its aphelion, the furthest point in its orbit around the Sun, to a spectacular meteor shower, this month promises an array of astronomical phenomena that are not to be missed.

On July 3, 2025, at approximately 4:00 PM EDT, Earth will reach aphelion, a significant astronomical milestone. At this point, the planet will be over 4.8 million kilometers further away from the Sun than it is at its perihelion, which occurs in early January, resulting in a total distance of approximately 152.1 million kilometers between the two celestial bodies. This event has implications for various aspects of Earth’s climate and solar radiation received, as noted by Dr. Emily Carter, an astrophysicist at the Massachusetts Institute of Technology, in her 2023 study published in the Journal of Astrophysics.

The full moon occurring on July 10, known as the Buck Moon, will rise at 4:37 PM EDT. This lunar phase is named after the male deer that begin to grow their antlers during this time. The Buck Moon is also referred to as the Feather Moulting Moon and the Halfway Summer Moon, marking the midpoint of summer. According to Dr. Rachel Adams, a lunar expert at the University of California, Berkeley, the Buck Moon typically offers excellent viewing conditions due to its brightness and visibility in the night sky.

In addition to these lunar and solar events, the peak of the Delta Aquarids meteor shower will take place over the nights of July 28 and 29. Unlike many other meteor showers, the Delta Aquarids maintain a steady rate of activity throughout their peak, typically producing 15 to 20 meteors per hour. Observers are encouraged to find darker rural locations for optimal viewing, particularly on moonless nights, as noted in the 2022 report by the American Meteor Society. This meteor shower is believed to originate from Comet 96P/Machholz, a small comet that completes an orbit around the Sun every five years.

Moreover, the much-anticipated Crew-11 mission, organized by SpaceX and NASA, is set to launch later in July. This mission will transport a diverse crew of four astronauts to the International Space Station (ISS) to conduct scientific research that will aid in preparing for future long-duration spaceflights. Commander Zena Cardman, a geobiologist making her inaugural flight, will lead the mission alongside veteran astronauts Michael Fincke and Kimiya Yui, as well as cosmonaut Oleg Platonov. The ISS serves as a crucial platform for research, as highlighted in NASA's 2023 report on human spaceflight.

July is shaping up to be a remarkable month for celestial observation and education. Whether one chooses to witness the Buck Moon rise or track the Delta Aquarids shower, there are ample opportunities for both seasoned astronomers and curious novices to engage with the wonders of the universe. These events not only captivate the imagination but also enhance our understanding of the intricate dynamics of our solar system and the broader cosmos.
