This recently discovered, ‘house-size’ Asteroid 2025 KF will pass closer to the Earth than the moon tonight, as reported by
Space.com
According to
The Sky Live, it is currently at around magnitude 17 in the constellation Hydra. The interactive star map gives updated estimates. My calculations suggest it is moving at around 1/2 degree every few minutes, so I think it should be noticeable against the background stars with a larger aperture.
Closest approach will be around 3:30am AEST, 3:00am ACST, 1:30am AWST.
Unfortunately, it is cloudy in Melbourne at the moment and the satellite images suggest cloud cover across Eastern Australia tonight. Maybe Western Australians may be able to catch this one with a good aperture in the evening before the moon rises?
I would be interested to know from experienced others whether chasing these types of things down for visual observation is realistic. I may not catch it this time, but your thoughts on the best way of approaching these Near Earth Objects would be helpful for next time.
