0.000 HBDAngular asteroid passed Earth on February 6
<html> <p>9 days ago I wrote post about <a href="https://steemit.com/science/@busser/what-happens-when-asteroid-turns-to-meteorite"><strong>asteroid danger</strong></a> for our Earth. 6 days after, sizeable and very strange space rock was observed in the near-Earth space</p> <p>Relatively small asteroid 2017 BQ6 passed Earth by 2.5 millions kilometers on Feb. 6 at 10:36 p.m. PST (1:36 a.m. EST, Feb. 7). For its observation was used radar: 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. The most interesting thing about 2017 BQ6 is its unusual angular form. Of course radar images are not so sharp as optical, but it is all what we have now:</p> <p><img src="https://img-fotki.yandex.ru/get/46400/214291281.f9/0_221098_179f9d9e_orig.jpg" width="1000" height="600"/></p> <p>Image: <a href="http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA21452">JPL</a></p> <p>Said Lance Benner of NASA's Jet Propulsion Laboratory in Pasadena, California:</p> <blockquote>The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders Asteroid 2017 BQ6 reminds me of the dice used when playing Dungeons and Dragons. It is certainly more angular than most near-Earth asteroids imaged by radar. </blockquote> <p>This boulder has size about 200 meters along its longest axis and rotates every 3 hours.</p> <p><img src="https://img-fotki.yandex.ru/get/58016/214291281.f9/0_221097_d3a50274_orig.jpg" width="1045" height="800"/> Image: <a href="http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA21453">JPL</a></p> <p>2017 BQ6 was discovered on Jan. 26 by the NASA-funded Lincoln Near Earth Asteroid Research (LINEAR) Project </p> <p>In case if it would crush into Earth, we would have only 11 days to prepare. To evaluate possible damage, such asteroid could do, you may use popular site<strong> </strong><a href="http://nuclearsecrecy.com/nukemap/"><strong>Nukemap</strong></a>, which shows nuclear bomb burst results. Just point the mark to the place on the map (for example, house of your enemy) and enter a yield (in kilotons)- for this boulder it is about 100 Mt = 100 000 kt. As it is unknown (not enough data about velocity and angle), whether it will burst in the atmosphere, or impact the surface, you can try both options. Results will be impressive.</p> </html>
