Asteroid 2 Pallas reaches opposition in Cetus with magnitude 8.3 brightness
Asteroid 2 Pallas has reached opposition in the constellation Cetus the Whale, shining at magnitude 8.3 and offering backyard observers a clear target visible all night through binoculars or small telescopes, Astronomy magazine senior editor Alison Klesman reported. Standing roughly 20 degrees above the southwestern horizon by 10 P.M. local daylight time, the main-belt asteroid serves as an accessible target for amateur astronomers tracking its slow drift against a background field star.
Saturn and Cetus star charts help locate Pallas
Stargazers can find Pallas by utilizing Saturn as a navigational anchor in the night sky. While Saturn sits in northern Cetus, Pallas occupies the center of the constellation, positioned about 5.4 degrees southeast of the magnitude 3.5 star Eta Ceti. Observers can locate the asteroid at 10 P.M. by dropping a little less than 19 degrees downward from Saturn toward the horizon. Pallas glows at magnitude 8.3 and sits approximately one-quarter of a degree northeast of an 8.2-magnitude field star of nearly identical brightness, according to Astronomy.
Tracking the nightly motion against background stars
The asteroid moves slowly southwestward at a rate of only a few arcminutes per night, closing the gap with its nearby field star over the course of an evening. Observers taking photographs every few hours can detect this gradual shift. By the following night, Pallas and the neighboring field star swap positions entirely, leaving the asteroid situated to the southwest of the star as it continues pulling away over subsequent nights, Astronomy reported.
Frequently asked questions about observing Asteroid Pallas
What equipment do I need to see Asteroid 2 Pallas?
Observers can spot Pallas using binoculars or any size telescope. At magnitude 8.3, it is too faint for the naked eye but easily reachable with basic optical aid under clear skies.
What time of night is best to view the asteroid?
Pallas is visible all night during opposition, reaching its highest point around 1 A.M. local time. It achieves an altitude of 20 degrees above the southwestern horizon by 10 P.M.
How fast does Pallas move across the background stars?
Pallas drifts southwest at a rate of only a few arcminutes per night. This slow motion becomes distinct when comparing images or observations taken 24 hours apart.
