Asteroid 2004 bl86 online dating
This technique uses the seemingly chaotic radar pattern reflected by the uneven surface of an asteroid as it sweeps across the surface of the Earth to determine how fast and in what direction it's tumbling.Once analyzed, these data will also reveal important details about its internal physical properties and future trajectory.27, 2014, reveal the asteroid's surface features in unprecedented clarity.Radar image of asteroid 2004 BL86 made by the Green Bank Telescope from radar transmitted from NASA's Goldstone Deep Space Network antenna.
Radar Speckles Unlock Other Details Concurrently with the radar imaging, the scientists also used the radar transmitter at the Arecibo Observatory in Puerto Rico and a portion of the antennas that are part of the National Radio Astronomy Observatory's (NRAO) Very Long Baseline Array (VLBA) to perform an observation known as radar speckle tracking.
The reflected signal was then received by the 100-meter diameter dish of the GBT in a process known as bistatic radar imaging.
The GBT images also confirmed the presence of a small moon-like companion zipping around the asteroid, which was previously detected with ground-based optical telescopes by Joe Pollock of Appalachian State University in Boone, North Carolina, and Petr Pravec of Ondrejov Observatory in the Czech Republic.
It reveals clear surface features and a companion moon-like body.
A team of astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia and NASA's Deep Space Network radar transmitter at Goldstone, California, has made the most detailed radar images yet of asteroid 2004 BL86.
