Mac as you always say, you must put down the image details.
very nice image

Mac, if you ran it through SpaceNow's HMIR you might be able to extract a lot more detail ;-)

Yes, a reprocess is needed  :D

#Insert tongue in cheek#

Sorry Julian I forgot the most important thing, details.


                           .

                         .

                       .

                     .




Its a crop from Nikon D3, with home made fish eye,
whilst being chased through a field by cows,
f45 1/2000s iso 256000,

Here is some detail i have managed to grab using said processing.

.


as you can see, there appears to be some sort of rocky outcrop,
sorry , that's just dust on my screen.

Mac.

Never, ever, argue with an idiot. They'll drag you down to their level and beat you with experience.

Small Asteroid Will Pass Earth Safely on Thursday

Small Asteroid Will Pass Earth Safely on Thursday

An asteroid about 25 feet (8 meters) across will safely pass Earth at about 1:21 p.m. PST (4:21 p.m. EST) today, March 6, approaching us six times closer than the moon.

This distance, though not unusual, is closer than the Earth flyby of a larger asteroid on Wednesday afternoon, March 5.

This afternoon's flyby object, asteroid 2014 EC, was discovered on March 5 by the Catalina Sky Survey near Tucson, Ariz. Its closest-approach distance, about 38,300 miles (61,600 kilometers), is between four and five Earth-diameters away from our home planet. It will not be visible to the unaided eye.

Giant Telescopes Pair Up to Image Near-Earth Asteroid 2014 HQ124

NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8, 2014, the new views of the object designated "2014 HQ124" are some of the most detailed radar images of a near-Earth asteroid ever obtained.

Computing Paths to Asteroids Helps Find Future Exploration Opportunities

NASA is developing the capabilities needed for astronauts to reach Mars in the 2030s.

To test these new technologies, the agency is planning a mission to identify, capture and redirect an asteroid to a stable orbit around the moon in the 2020s, which astronauts will visit. NASA is studying candidate asteroids for the Asteroid Redirect Mission (ARM). One of the systems that helps to identify such an asteroid is the Near-Earth Object Human Space Flight Accessible Targets Study (NHATS) developed and maintained at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

NHATS is an automated system that uses specialized computer algorithms to compute spacecraft trajectories for possible round-trip mission opportunities to visit a Near-Earth Asteroid (NEA). It is the first study to perform a thorough investigation of NEA accessibility for human space flight and the only automated accessibility monitoring system of its kind in the world. After two years of operation, NHATS has identified more than 1,000 NEAs that could be destinations for future robotic or human missions, enabled by future technology. In the near-term, some of them could be potential candidates for the ARM mission.

Map Data Shows Frequency of Small Asteroid Impacts

Newly Released Map Data Shows Frequency of Small Asteroid Impacts, Provides Clues on Larger Asteroid Population

 It happens all the time: small asteroids impact Earth's atmosphere

Small asteroids near Earth, with sizes of only about a meter, hit the atmosphere and disintegrate with surprising frequency - around every other week, new data show.

Data gathered by U.S. government sensors and released to NASA for use by the science community reveal that these small impact events are frequent and random. A map of these small impact events - known as fireballs or bolides - recently released by NASA shows the frequency and approximate energy released by bolide events detected from 1994 through 2013. It dwarfs a data-base of small impacts based on infra-sound detections released last fall, but it does not contain all fireballs - objects less than a meter in size - that impacted the Earth during this period.

Asteroid to Fly By Earth Safely on January 26

Asteroid to Fly By Earth Safely on January 26

An asteroid, designated 2004 BL86, will safely pass about three times the distance of Earth to the moon on January 26. From its reflected brightness, astronomers estimate that the asteroid is about a third of a mile (0.5 kilometers) in size. The flyby of 2004 BL86 will be the closest by any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027.

At the time of its closest approach on January 26, the asteroid will be approximately 745,000 miles (1.2 million kilometers) from Earth.

"Monday, January 26 will be the closest asteroid 2004 BL86 will get to Earth for at least the next 200 years," said Don Yeomans, who is retiring as manager of NASA's Near Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, after 16 years in the position. "And while it poses no threat to Earth for the foreseeable future, it's a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more."

Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86. The images show the asteroid, which made its closest approach today (Jan. 26, 2015) at 8:19 a.m. PST (11:19 a.m. EST) at a distance of about 745,000 miles (1.2 million kilometers, or 3.1 times the distance from Earth to the moon), has its own small moon.

The 20 individual images used in the movie were generated from data collected at Goldstone on Jan. 26, 2015. They show the primary body is approximately 1,100 feet (325 meters) across and has a small moon approximately 230 feet (70 meters) across. In the near-Earth population, about 16 percent of asteroids that are about 655 feet (200 meters) or larger are a binary (the primary asteroid with a smaller asteroid moon orbiting it) or even triple systems (two moons). The resolution on the radar images is 13 feet (4 meters) per pixel.

I find the fact this small asteroid has a moon orbiting it amazing. Mind blown.
