2007 VK184

 is a sub-kilometer asteroid, classified as a near-Earth object of the Apollo group, and estimated to be approximately 130 m in diameter. It was listed on the Sentry Risk Table with a Torino Scale rating of 1 for a potential impactor in June 2048. It was removed from the Sentry Risk Table on 28 March 2014.

2023
The asteroid will come to opposition on 24 April 2023 when it will have a solar elongation of 177 degrees and an apparent magnitude of 22. Then on 15 July 2023 the asteroid will harmlessly pass 0.2275 AU from Earth.

Description
was discovered on 12 November 2007 by the Catalina Sky Survey. It was recovered on 26 March 2014 by Mauna Kea, and removed from the Sentry Risk Table on 28 March 2014. By 4 January 2008, with an observation arc of 52 days, there was a 1 in 2700 chance of an impact with Earth on 3 June 2048. The Sentry Risk Table, using an observation arc of 60 days, showed the asteroid had a 1 in 1820 chance (0.055%) of impacting Earth on 3 June 2048. Since the March 2014 recovery, it is known that the asteroid will pass 0.013 AU from Earth on 2 June 2048.

2014 passage
Before the 2014 close approach, the asteroid had a modest observation arc of 60 days, and the imprecise trajectory of this asteroid was complicated by close approaches to Earth, Venus and Mars. On 23 May 2014, the asteroid passed 0.17 AU from Earth and reached an apparent magnitude of ~20.8. As expected the close approach allowed astronomers to recover the asteroid on 26 March 2014 and refine the odds of a future collision. As the asteroid gets closer to Earth, the positional uncertainty becomes larger. By recovering the asteroid well before closest approach you can avoid searching a larger region of the sky. Most asteroids rated 1 on the Torino Scale are later downgraded to 0 after more observations come in.

Risk assessments were calculated based on a diameter of 130 meters. It was estimated that, if it were ever to impact Earth, it would enter the atmosphere at a speed of 19.2 km/s and would have a kinetic energy equivalent to 150 megatons of TNT. Assuming the target surface is sedimentary rock, the asteroid would impact the ground with the equivalent of 40 megatons of TNT and create a 2.1 km impact crater. Asteroids of approximately 130 meters in diameter are expected to impact Earth once every 11000 years or so.

2048
On 26–27 March 2014, additional observations were made which ruled out the chance of an impact in 2048. On 2 June 2048 the asteroid will pass 5 lunar distances from Earth with a 3-sigma uncertainty region of ±$3,300,000,000 kg$.

2118
By the Earth approach of June 2118 the known approaches become more divergent.
