When you look up maybe you can catch sight of asteroid 2015 TB145. (with a telescope)
I think we are getting better at finding these asteroids sooner but a good thing it is going to miss and too bad we can't stick a transponder on it.

NASA Spots the 'Great Pumpkin': Halloween Asteroid a Treat for Radar Astronomers
October 21, 2015NASA scientists are tracking the upcoming Halloween flyby of asteroid 2015 TB145 with several optical observatories and the radar capabilities of the agency's Deep Space Network at Goldstone, California. The asteroid will fly past Earth at a safe distance slightly farther than the moon's orbit on Oct. 31 at 10:05 a.m. PDT (1:05 p.m. EDT). Scientists are treating the flyby of the estimated 1,300-foot-wide (400-meter) asteroid as a science target of opportunity, allowing instruments on "spacecraft Earth" to scan it during the close pass.
Asteroid 2015 TB145 was discovered on Oct. 10, 2015, by the University of Hawaii's Pan-STARRS-1 (Panoramic Survey Telescope and Rapid Response System) on Haleakala, Maui, part of the NASA-funded Near-Earth Object Observation (NEOO) Program. According to the catalog of near-Earth objects (NEOs) kept by the Minor Planet Center, this is the closest currently known approach by an object this large until asteroid 1999 AN10, at about 2,600 feet (800 meters) in size, approached at about 1 lunar distance (238,000 miles from Earth) in August 2027.
The gravitational influence of the asteroid is so small it will have no detectable effect on the moon or anything here on Earth, including our planet's tides or tectonic plates.

Asteroid to narrowly miss Earth on HalloweenPosted: Oct 21, 2015 8:09 AM PDT
Updated: Oct 21, 2015 8:10 AM PDT
(CNN) -- Don't look now, but an asteroid is heading our way on Halloween.
On the other hand, go ahead and look. As it misses Earth by about 300,000 miles (slightly farther away than the moon), the asteroid, named 2015 TB145, will be visible to those with good telescopes -- and NASA, which announced the discovery.
Calling it "one of the best radar targets of the year," a Jet Propulsion Laboratory report on the asteroid said that "the flyby presents a truly outstanding scientific opportunity to study the physical properties of this object."
The asteroid will be traveling through Orion on October 30-31.
It's a good thing it will miss, though. The asteroid is estimated to be 300 to 600 meters wide and traveling at 78,000 mph. By comparison, the meteorite that exploded in the sky over Chelyabinsk, Russia, in 2013 was about 20 meters wide.

Goldstone Radar Observations Planning: 2009 FD and 2015 TB145...
2015 TB145
2015 TB145 was discovered on 2015 Oct 10 by the Pan-STARRS I survey. The object will approach the Earth
within 0.00326 au (1.3 Lunar distances or about 490 000 km) on 2015 Oct 31 at about 17:00 UT (10 AM PDT).
The asteroid is in an extremely eccentric (~0.86) and
high inclination (~40 deg) orbit. It has a Tisserand parameter of 2.937 hinting that it may be
cometary in nature. Its absolute magnitude of 19.8 indicates that its diameter is probably within a factor of two
of 320 meters. At closest approach the SNRs/run at DSS-14 are expected to be over 20000, so this should
be one of the best radar targets of the year. We hope to obtain images with a range resolution as high
as 2 m/pixel using DSS-13 to transmit and Green Bank (and possibly Arecibo) to receive. The flyby presents
a truly outstanding scientific opportunity to study the physical properties of this object.
The encounter velocity is 35 km/s, which is unusually high.
This is the closest approach by a known object this large until 1999 AN10 approaches within 1 lunar distance
in August 2027. The last approach closer than this by an object with H < 20 was by 2004 XP14 in July 2006 at
1.1 lunar distances.

How asteroids can help us reach Mars
(CNN)If you've read or seen "The Martian," you know that getting humans safely to Mars and back will be a gargantuan task.
Unlike a mission to the moon, which can be done in three or four days, a journey to Mars -- some 140 million miles away -- could take more than six months each way. For a trip that long, astronauts would need to set up a network of supply depots in deep space to refuel their spacecraft.
But how? As crazy as it sounds, one answer is -- asteroid mining.
