An asteroid larger than Manhattan is approaching Earth this week, providing a unique opportunity for astronomy enthusiasts. This phenomenon, rare and spectacular, will not recur for several decades.
Discovered in 1918, asteroid 877 Alinda is one of the largest to hit our planet this century. Although it presents no danger, its increase to 12 million kilometers of the Earth makes it an event not to be missed. Amateurs will be able to observe it with binoculars or follow a live broadcast.
An exceptional celestial spectacle
This Sunday is the ideal time to observe Alinda, according to astronomers. With a magnitude of 9.4, the asteroid will not be visible to the naked eye, but 10×50 binoculars will be enough to see it. In France, it will appear around 6:40 p.m., peaking at 67° abovehorizon south around midnight.
Alinda heads towards the constellation Gemini, providing a clear landmark for observers. Her positioning optimal allows it to appear with good brightnessbecause the asteroid is aligned with Earth and the Soleil.
An observation accessible to all
For those who prefer to stay warm, the Virtual Telescope Project offers a live broadcast this Sunday. This initiative allows everyone to enjoy the event without specialized equipment.
The asteroid will remain visible for eleven days, but Sunday marks its peak in terms of brightness and positioning. An opportunity to be seized, because Alinda will not return this close to Earth before 2087.

A harmless asteroid
Classified as near-Earth objectAlinda poses no threat to our planet. Her orbitalthough close, does not cross that of the Earth. With a diameter estimated at 4.2 kilometers, it is one of the five largest asteroids to approach us by 2200.
Its slow rotation, approximately 28 hours for a complete revolution, and its elliptical orbit around the Sun make it an interesting subject of study for astronomers.
