On November 30, 2023, the near-Earth asteroid (433) Eros will pass within two degrees of the Andromeda Galaxy, offering a unique opportunity for skywatchers to observe this celestial event. The Virtual Telescope Institute, in collaboration with the Asteroid Foundation, will host a live stream of this event, featuring expert commentary and real-time views from telescopes located in Manciano, Italy.
The livestream is set to begin at 3 p.m. EST (2000 GMT). Viewers can expect insights from Gianluca Masi, founder of the Virtual Telescope Project. This event not only showcases the beauty of Andromeda but also highlights the significance of near-Earth asteroids. Masi stated, “Having such an important near-Earth asteroid just a couple of degrees away from the legendary Andromeda Galaxy is a precious opportunity to share both the importance of these minor planets and the beauty of our cosmic neighbor.”
Eros, discovered in 1898, was the first near-Earth asteroid identified. It was later visited by NASA’s NEAR (Near Earth Asteroid Rendezvous) Shoemaker spacecraft, which marked a significant milestone in space exploration. The spacecraft orbited Eros before achieving the first asteroid landing in history on February 12, 2001.
Details of the Celestial Event
When Eros passes, it will be approximately 37 million miles (60 million kilometers) from Earth, while the Andromeda Galaxy will be located about 2.5 million light-years from our solar system. Observers can look forward to seeing Eros shine at around magnitude 10 for several weeks, making it visible even through smaller telescopes, such as those with a 60 mm aperture.
Masi noted that magnitude is the scale astronomers use to measure an object’s brightness: the lower the number, the brighter the object appears. This means that Eros will be particularly easy to spot during its pass.
For those wanting to catch a glimpse of this event, both Eros and Andromeda will be positioned high above the eastern horizon following sunset on November 30. Skywatchers can use the constellation Cassiopeia as a guide to locate Andromeda. By identifying the uppermost three stars of Cassiopeia, observers can find their way to the Andromeda Galaxy.
Prepare for the Viewing
This live event represents an exciting opportunity for astronomy enthusiasts and anyone curious about the wonders of the universe. Those interested in enhancing their stargazing experience might consider exploring binoculars or telescopes tailored for observing distant solar system objects, especially as we approach the new year.
As the excitement builds for this cosmic encounter, the collaboration between the Virtual Telescope Institute and the Asteroid Foundation underscores the importance of public engagement in science and astronomy. Make sure to tune in to witness this extraordinary event unfold in real time.
