ImageThe tiny moon S/2026 (44) 1, marked with a pink arrow, around asteroid (44) Nysa. The previously unknown moon, designated S/2026 (44) 1, has been independently identified during two separate campaigns using high-contrast imaging to distinguish it from the brightness of the primary asteroid. Speculation is that the asteroid (44) Nysamay have formed through low-velocity reaccumulation of remnants torn away during a collision before it reached its current location in the asteroid belt.
