2 Pallas

Small pieces of rock, with a big influence (just ask the dinosaurs).

2 Pallas

Post by Christopher K. »

Heinrich Olbers found Pallas, only the second asteroid discovered, on this day in 1802.

We can find Pallas with a small telescope by looking in Equulleus beginning around 9 April. On that morning, at 4:20am, there will be about an hour of darkness left as this tiny constellation rises in the east. Pallas will be less than a degree of the M-class magnitude 5.8 star 9 Equulei. Starry Night Pro Plus currently has Pallas' magnitude at 9.8. It should brighten through the spring and summer.

Pallas will move into Pegasus on 14 or 15 April.

The bad weather prevented Baton Rougeans from seeing Pallas during its actual opposition of 6 April, but the asteroid looks great at least through the 14th.

Below are the times that Pallas will be thirty degrees off the horizon...
9 April = 9:29pm
10 April = 9:24pm
11 April = 9:18pm
12 April = 9:13pm
13 April = 9:08pm
14 April = 9:03pm
It will probably range from magnitude 8.1 to 8.2.

Tonight Pallas will be 0˚25' east-southeast of the magnitude 2.6 G-class Muphrid.

HRPO personnel will try its collective hand at showcasing 2 Pallas to visitors on Saturday 11 May from 9:30pm to 10:30pm. At that time the asteroid will be about magnitude 7.5 and (if in a two-degree field-of-view) will be found 0˚36' SSE of magnitude 6.1 G-class HIP66086.

Pallas will be viewed Monday night at HRPO (although only from 10pm to 10:30pm) during the peak of the Perseid Meteor Shower. It will be in the constellation Boötes, 1˚43' WSW of the magnitude 4.2 K-class 20 Boötis.

On 11 May Pallas will be stationary in its orbit, but the orbit itself certainly doesn't remaning stationary in relation to the Earth. In one is of a mind to search for a mag 9.1 asteroid, Pallas can be found early Monday morning at 1:15am right behind the arrow of Sagitta, just 0˚35' NW of G-class mag 4.4 Alpha Sagittae.

Pallas shifts with its orbit into Vulpecula probably around the morning of the 19th.
