How to Spot Tomorrow Night’s Asteroid Flyby

Tomorrow night , near - Earth asteroid 2005 YU55 will pass between our major planet and the orbit of the moon , coming within 0.85 lunar distances of the Earth ’s surface as it course along its electron orbit . uranologist say the target , which measure about 400 meters in diam , is the orotund asteroid to fly this nigh to place in 35 old age .

2005 YU55 is a character - c ( i.e. carboniferous ) asteroid , meaning its surface is dark-skinned . This will make the asteroid insufferable to see with the naked eye , but scientist say skywatchers with the right equipment should be able-bodied to catch a glance of the massive rock as it zip up by Earth . Here ’s how you could spot it for yourself .

Next , you ’ll need to do it when to look . NASA ’s estimates indicate that the asteroid ’s near approach to Earth will come about tomorrow dark at 23:28 UT , or 06.28 p.m. EST .

The aim will in all likelihood be best look from Western Europe and North America ; according to Scott Fisher , curriculum conductor of the National Science Foundation ’s Division of Astronomical Sciences , stargazer on the East Coast of the US will have the good dig of spying the aim at its closest power point of plan of attack .

Finally , you ’ll need to bed where to indicate your scope . According to Sky & Telescope Magazine , 2005 YU55 will traverse the 70 ° of sky eastward from the constellation Aquila to cardinal Pegasus in just 10 hours . This means it ’ll be move at a somewhat decent cartridge holder , which will in all probability make it harder to descry , but here ’s a elaborated chart , along with instructions from Sky & Telescope on how to witness the asteroid ( click the image below to expound the chart ):

Asteroid 2005 YU55 will race far across the configuration in just 11 time of day . The box on the top chart [ the dark gamey constellation map with the yellow path line ] express the arena of the closeup above . There , the asteroid is plotted for just over an hour on the eventide of November 8th for North America ( from 1:51 to 3:12 November 9th Universal Time ) . North is up , east is left . On each of the little upside - down map of the U.S. , put a pencil acid on your positioning . These are the asteroid ’s patent spatial relation at 2:00 and 3:00 UT for your web site . link your dots with a straight line paralleling the argument plotted , which is for Kansas .

Those with the astronomical know - how can look up the asteroid ’s coordinate for any given sentence on theJPL Solar System Dynamics website , and stargazing yellowish brown with more high powered equipment ( 10—12 column inch scopes , CCD camera , profesional filter , etc . ) are further to help astronomer get more detailed brightness measure of the asteroid ( details can be foundhere ) .

That ’s all the oecumenical information you ’ll need to start your asteroid search . Do n’t draw a blank to avoid light pollution whenever possible — you ’ll already be fighting the full lunar month to arrest a coup d’oeil of the asteroid .
