Short Talk:

“Astronomy Day Re-Cap,” Discussion from RAS members

  • Descriptions of photos taken during Astronomy Day on Saturday, April 28
  • Last minute changes due to cultural day events at the museum forced a change of location, but there was still a large turnout even though RAS ended up behind the museum.  Displays included meteorite skymap, dark sky information,Sydney’s telescope and Science Fair project, Starlab, City Dark movie, Russ the roving astronaut, and 16 water bottle rocket launches.
  • Further Astronomy Day discussion included comments on the status of RAS/SMV relations.  Are we being treated right?  Are we low on the totem pole?  Rich Conti came by the RAS activities area and talked about 10 minutes.  Were the Astronomy Day activities used as a draw for the SMV attendance?
  • Astronomy Day – Belmead evening event (indoor sky orientation was a lot of fun, RAS information, dark sky info, night skywatch was clouded out).  Several good questions from the small crowd that attended.  The public was invited back on June 30th.  Attendees included Jim Browder, Laura Graham, and Demetrius Venable (HowardUniversity astronomer who lives in Powhatan).
  • Thanks to Prashant for planning another successful Astronomy Day!!  Great work Prashant!!

Major Presentation:

“Asteroids, Friend or Foe,” Betty Wilson

An asteroid is defined as a metallic rocky body between the orbits of Mars and Jupiter.  Research into asteroids is done because these objects are pure material from the beginning of time.  They are categorized by their composition: carbon-based (C),  Silicates (S), and other metallic types (M), including nickel ion.

The first asteroid seen was Ceres, seen in 1801.

Many people are worried that Earth will be hit by a stray asteroid and cause a cataclysmic disaster.  Scientists (and movies) have studied different ideas to deflect asteroids and other objects on a line of collision with us.  Some of the deflection strategies are ‘kinetic impacts’, SpaceTug, Nuclear explosions, Mirror bees, and lasers.

Asteroids are small, but they have been observed with binoculars and telescopes.  ASL Asteroid Program is software that has demonstrated how asteroids move and interact with other objects due to gravity and other forces.

 The first Near-Earth object was named Eros and was seen by Witt inBerlin.  It was estimated to be approximately 21 miles by 8 miles. 

Agencies have found and are tracking 911 asteroids.  NASA has identified 93% of the large ones.

Several have been tracked by WISE (Wide field Infrared Survey Explorer).  One of those tracked was 2008 TC3.  It was the size of a VW bus, and was tracked until it crashed into the Sudan Nubian Desert.   Another, 2005 YU55, was tracked as it passed within the moon’s orbit on 11/8/11.  Two others were detected that close in 2011 and 2012.
