An Unexpected Encounter — M95, M96 and (11) Parthenope
On the night of February 21–22, 2023, I was imaging the spiral galaxies M95 and M96 in Leo, about 30 million light-years away.
While processing the data, I noticed a moving object crossing the field.
It was asteroid (11) Parthenope, a 150-km main-belt asteroid between Mars and Jupiter. That night, it was near opposition, at 1.7048 AU (≈255 million km), appearing close to its maximum brightness (mag ~10).
