Comet Arend-Roland
A long-period comet discovered in November 1956, by Belgian astronomers Silvain Arend (1902-1992) and Georges Roland (1922-1991). It reached perihelion (0.32 AU) on April 8, 1957, passed within 0.57 AU of Earth on April 21, and reached a maximum brightness of magnitude -1.

Comet Arend-Roland developed a tail up to 30° long in photographs and a prominent spike-like antitail. Its orbit was hyperbolic (eccentricity 1.0002) with an inclination of 119.9°.
