It's an article from Sky and Telescope, apparently.

HEFTY ASTEROID TO SWEEP NEAR EARTH

Next month a newly discovered asteroid will pass close enough to Earth to
be easily spotted in small telescopes and even binoculars. According to
calculations by Gareth V. Williams, associate director of the Minor Planet
Center in Cambridge, Massachusetts, the asteroid's August 18th flyby
should bring it to within 530,000 kilometers (330,000 miles) of Earth,
just outside the Moon's orbital distance....

Still quite faint at magnitude 18, 2002 NY40 is making a very tight loop
around the star Beta Aquarii. During the next few weeks it will brighten
tremendously and yet remain almost motionless in the sky -- the eerie
signature of an asteroid hurtling right toward Earth! On the night of
Saturday, August 17th, 2002 NY40 should reach magnitude 9.3 when well
placed for viewing from North America. At that time its angular velocity
will exceed 4 arcminutes per minute, a motion easily perceptible in small
telescopes. SKY & TELESCOPE plans to issue detailed observing
instructions, through AstroAlerts and SkyandTelescope.com, in the days
leading up to this rare event....

While there is no danger of 2002 NY40 striking Earth during this flyby, a
future impact has not been ruled out. Both NEODyS, operated by the
University of Pisa, and NASA's Near-Earth Object Program have identified a
number of very close encounters in the years to come. These occur either
around August 18th as the asteroid heads in toward the Sun, or near
February 14th when on its way out. Both agencies are focusing on a flyby
just 20 years from now (on August 18, 2022), when there appears to be a
1-in-500,000 chance of an impact -- extremely unlikely, but worrisome just
the same....
