The chart below shows where to pinpoint Pallas. March was when Pallas was closest and brightest; it shone at magnitude 7.1 around the time it reached opposition on March 23rd.In April Pallas is up in good view as soon after dark as you care to look, but it fades from 7.3 to 8.2 during the month. In May it dims further, to magnitude 8.9 by month’s end. By the end of June it’s 9.4.
During much of this time, especially in late March and early April, Pallas is crossing the vast Virgo Galaxy Cluster — most of whose members are at least a couple of magnitudes fainter and require a bigger telescope to be seen.
Pallas is about 525 kilometers in diameter — “minor” as planets go, but a very substantial world in its own right nevertheless. As you look, consider that the stars shining behind it are more than a million times farther away — and that the Virgo Cluster galaxies are nearly a million times still farther behind the stars.
