It’s been a busy two months. The end of one semester the beginning of a new semester, but I wanted to share a bit of good news for myself. I’m now official part of the solar system, While there have been some people who wished they could send me into orbit the picture,as you can see below, does not quite mean I’m there yet.
It does mean I’ve just got an asteroid named after me! It’ s a main belt asteroid between Mars and Jupiter, with a maximum magnitude of 15. My thanks to Robert Holmes, director of the ARI observatory, and an adjunct faculty member in the physics department at EIU, who discovered the asteroid and did the naming.
The official designation is 128925 Conwell or 2004 TJ70. You can see more information on this asteroid at NASA’s Jet Propulsion Lab (JPL) site:

(From NANCY ATKINSON at Universe Today):A newly discovered house-sized asteroid will miss the Earth by less than 17,700 km (11,000 miles) on Monday June 27, 2011. That’s about 23 times closer than the Moon. The size and location of the asteroid, named 2011 MD, should allow observers in certain locations to take a look at the space rock, even with small telescopes. It’s closest approach will be at 13:26 UTC on June 27.
According to Skymania, 2011 MD was found just yesterday, June 22, by LINEAR, a pair of robotic telescopes in New Mexico that scan the skies for Near Earth Asteroids.
As of now, asteroid 2011 MD is estimated to be between 9 to 45 meters (10 to 50 yards) wide. Dr. Emily Baldwin, of Astronomy Now magazine, said there is no danger of the asteroid hitting Earth, and even if it did enter the atmosphere, an asteroid this size would “mostly burn up in a brilliant fireball, possibly scattering a few meteorites.”
To find out updated information on 2011 MD’s ephemeris, physical parameters and more, including an orbit diagram and close-approach data, see this page on JPL’s Solar System Dynamics website.

NEW PODCAST: Probing the Kuiper Belt and Beyond June 17, 2011

Description: Meg and Brooke discuss what we have learned by studying the small planetesimals orbiting beyond Neptune in the Kuiper belt and beyond. In particular they discuss Sedna, a roughly Pluto-sized body on a highly eccentric orbit beyond Neptune that challenges our understanding of the solar system and suggests the presence of a distant icy population of bodies residing beyond the Kuiper belt. They discuss the possible origin of Sedna’s orbit and the search for more Sedna-like bodies.
Bio: Meg Schwamb is National Science Foundation (NSF) Astronomy & Astrophysics Postdoctoral Fellow at Yale University’s Center for Astronomy and Astrophysics (YCAA). As part of the La Silla-QUEST KBO Survey (http://hepwww.physics.yale.edu/lsqkbo), she is searching the southern skies for the largest and brightest members of the Kuiper belt and beyond, and studying the orbital and physical characteristics of these new discoveries. Meg is also studying the processes of planet formation and evolution as project scientist for Planet Hunters (www.planethunters.org), a citizen science project searching for the signatures of transiting exoplanets in the data collected by NASA’s Kepler mission.
Brooke Simmons is a researcher at the Yale Center for Astronomy & Astrophysics, studying the mechanisms by which black holes and galaxies co-evolve over cosmic time. Currently, her research focuses on extending our understanding of galaxies hosting actively growing supermassive black holes to a time when the universe was less than a quarter of its present age. Brooke is also actively involved in Galaxy Zoo (www.galaxyzoo.org), a citizen science project that invites the public to participate in forefront scientific research.
Video of 2010 TD54 Near Miss Today. October 12, 2010

Amateur astronomer Patrick Wiggins captured images this morning of the newly found asteroid 2010 TD54 that passed byEarth about 27,000 miles away. The asteroid was only detected this past Saturday. The film, which was made form a composite of 16 still pictures with a 5 second exposure., show the asteroid passing through the background sky, although moving along at 10.7 miles/s. Estimates are the asteroid is about 7.3 m wide, and contained the energy of about 22 kilotons of TNT, if it would have come crashing through Earth’s atmosphere. For this animation, the mount was set to allow the target to pass through the field of view, and includes 16 five-second exposures shot between 08:51:51 and 08:54:04 UTC. The streak is the asteroid and the length of the streak shows how far it travels relative to the background in 5 seconds.
UPDATE: October 12th Asteroid October 11, 2010

UPDATE (FROM UNIVERSE TODAY): Don Yeomans, Manager of NASA’s Near-Earth Object Program Office replied to an inquiry about the object and said the newly discovered NEO 2010 TD54 is approximately 5-10 meters in size, and is now predicted to pass about 46,000 km from Earth’s surface at about 07:25 EDT (11:25 UT) on Tuesday, Oct 12, 2010. It was discovered by Catalina Sky Survey on Saturday morning.
“Only 1 in a million chance of an impact,” Yeomans said, “and even if it does impact, it is not large enough to make it through the Earth’s atmosphere to cause ground damage.”

Astronomers are tracking the asteroid, 2010 TD54, and it’s orbit is expected to bring it within 36,000 (plus or minus 3000 ) miles from Earth on October 12, with closest approach at approximately 11:14 UT. Information is to be found at the IAU Minor Planet Center website. The size of the object has not known, but estimates say it is likely smaller than 10 meters.

Good news! Due to the wonderful work of Tyler Linder and the other students at Eastern we now have our own registered observatory code (H20) for the EIU observatory. Observatory codes are assigned by the Minor Planet Center (a service of the International Astronomical Union) for use in cataloguing astrometric observations of solar-system objects.

(PhysOrg and Universe Today): The Catalina Sky Survey near Tucson, Ariz., discovered both objects on the morning of Sunday, Sept. 5, during a routine monitoring of the skies. The Minor Planet Center in Cambridge, Mass., first received the observations Sunday morning, determined preliminary orbits and concluded that both objects would pass within the distance of the moon about three days after their discovery.
Two asteroids orbital path
Asteroids 2010 RX 30 and 2010 RF12 will make their closest approach to Earth this Wed. At time of closest approach for 2010 RX 30 (2:51 a.m. PDT), it will be approximately 154,000 miles (about 248,000 kilometers) above the North Pacific, south of Japan. At time of closest approach for 2010 RF12 30 (2:12 p.m. PDT ), the asteroid will be approximately 49,088 miles (about 79,000 kilometers) above Antarctica.
Near-Earth asteroid 2010 RX30 is estimated to be 32 to 65 feet (10 to 20 meters) in size and will pass within 0.6 lunar distances of Earth (about 154,000 miles, or 248,000 kilometers) at 2:51 a.m. PDT (5:51 a.m. EDT) Wednesday. The second object, 2010 RF12, estimated to be 20 to 46 feet (6 to 14 meters) in size, will pass within 0.2 lunar distances (about 49,088 miles or 79,000 kilometers) a few hours later at 2:12 p.m. PDT (5:12 pm EDT).

Between my daughter wedding and my trip back to Nebraska, I’ve been a little too busy to update the blog as often as I’d like. So let’s correct that.
http://365daysofastronomy.org/2010/06/19/june-19th-second-place-vesta/
Who remembers second place? It’s a problem that plagues anyone who isn’t the biggest or fastest or shiniest. In today’s episode of 365 Days of Astronomy, we look at the second largest object in the Asteroid Belt – Vesta.
