Comet Arend or 50P/Arend is a

perihelions with its last return of Earth recorded on November 1, 2007.[3][5][6][7][8] The comet's next perihelion will be in the year 2024.[9][10]

Observations

50P/Arend was observed at its brightest at a

astronomical units (AU) as it approached Jupiter in 1969, even if its maximum magnitude was 15. This approach also led to the comet's orbital period to increase to 8.0 years.[1]

Long-term motion studies conducted by

mean residual is at 0".60.[15]

The nucleus of the comet has a radius of 0.95 ± 0.03 kilometers, assuming a geometric albedo of 0.04.[16]
