1 ASTEROIDS

2 METHOD FOR IMAGING ASTEROIDS 1.Find the coordinates (ephemeris table) of where the asteroid is using JPL Horizons 2.Take images using the 16” RoR telescope using a Luminance filter 3.Open the images in DS9 4.Aligned the coordinates using Astrometry.net 5.Blinked the images and made a GIF of them

3 HERCULINA Discovered by Max Wolf in 1904 Inclination of 16.31° Exact mass uncertain 4.5 year orbit In main belt of asteroids About 260 km lengthwise, with a diameter of 225 km It is believed that Herculina is within the top 20 by size Not spherical “Resembles a beat up toaster” Has large craters

4 RESULTS: HERCULINA

5 PALLAS Discovered by Heinrich Wilheim Matthäus Olbers in 1802. Pallas is a carbonaceous chondrite/C-Type Asteroid (rocky asteroid) Average distance from sun of 2.77 AU, orbiting around the sun every 4.6 Julian years. Mean diameter of 544 km. Inclination of 34.8°, highly irregular 7.8 hour day Surface is a silicate material that is low in iron and water. Named after Pallas (Athena) Has a moon that orbits about 1km away.

6 RESULTS: PALLAS

7 JUNO Discovered by Karl L. Harding on September 1, 1804 Named after the Roman Goddess Juno Orbital period of 4.36578 years, and the average orbital speed is 17.93 km/s Temperature ranges from 163 K to 301 K. Apparent magnitude ranges from 7.4 to 11.55, with an absolute magnitude of a 5.33 (Artist Representation)

8 RESULTS: JUNO

9 DAVIDA Discovered by R. S. Dugan in 1903 C-type asteroid 4 x 10 19 kilograms 6th most massive asteroid 300 kilometer diameter 3.16 AU from the Sun Orbital period of 5.63 years Rotation period of 5.13 hours Near NGC 5792 in the sky Named after an astronomy professor

10 RESULTS: DAVIDA
