16 sky watching february 15 a near earth asteroid called 2012 da14 will pass very close to earth a near earth asteroid called 2012 da14 by astronomers will pass very close to earth on february 15 2013 astronomers estimate that when it s closest to us it ll be within the orbit of the moon which averages about a quarter million miles away and closer than some high orbiting communications satellites 2012 da14 will be about 17 200 miles 27 680 kilometers away it will not strike earth in 2013 astronomers calculations of asteroid orbits can be trusted after all even decades ago they knew enough about calculating orbits to send people to the moon and bring them safely back and today we are able place our space vehicles in orbit around objects as small as asteroids february 16 evening twilight mercury at greatest elongation east this is the best opportunity this year for observers in the northern hemisphere to observe mercury in the evening sky sweep the western horizon with binoculars to pick up mercury s tiny speck of light planets mercury will be well placed in the western sky for most of the month the best opportunity to see it as an evening star in 2013 venus is now very low in the southeast at sunrise mars has faded into the west moving behind the sun it rapidly crosses the entire constellation of aquarius this month jupiter remains in taurus close to aldebaran and the hyades it is high in the southern sky in the early evening and sets in the northwest around 2 a m saturn is spends the month in western libra it rises in the east at around midnight and is visible the rest of the night uranus is visible in pisces in the early evening and sets around 9 p m neptune is in aquarius all month becoming lost in the twilight close to the sun www hubblesite org
