Torino number of 1

[edit]

The 2007 VK184 article says that 2007 VK184 is the only object with a Torino number of 1 or higher, but the Torino Scale article says there are 3 objects that have positive Torino numbers. 69.140.152.55 (talk) 00:49, 4 June 2008 (UTC)[reply]

Hi. I've fixed the contradiction. The confusion resulted because the thrid (2008 AF4) object is no longer listed, and this object is the only one assesed for potential impacts within 100 years, and 1950 DA is rated above 0 (or maybe it's 2, I don't remember) but the main NEO risks page only lists objects within 100 years of potential impact. Let me know if this occurs again or if further problems arise. Thanks. ~AH1(TCU) 17:40, 4 June 2008 (UTC)[reply]

Orbital Trajectory

[edit]

The orbital trajectory of 2007 VK184 appears to take it extremely close to Venus in 2014. Is there any probability of an impact of this asteroid with Venus? Hurricanekiller1994 (talk) 21:56, 29 November 2009 (UTC)[reply]

Even though the orbit of VK184 passes near the orbit of Venus, JPL shows no current close passes of Venus over the next 100 years. Though having been observed only over a 60 day arc, the orbit is poorly known with a orbit quality of only 5 (0 would be best). -- Kheider (talk) 10:35, 30 November 2009 (UTC)[reply]

New Astroid

[edit]

I was wrongly accused of Vandalism. I made an edit stating that 2007 VK184 is NOT the only NEO listed above a level 0. This is a fact. 2011 AG5. I request an apology from the person who accused me and I also ask that I be allowed to re add that section. --Akemi Loli Mokoto (talk) 14:41, 19 February 2011 (UTC)[reply]

I am the one accusing you of vandalism. Sorry, but your edited look like vandalism. Your first edit removed a reference, linked to VK184, and claimed that the asteroid would only come within 0.76 LD of the Earth when it will come within 0.76 Earth radii. Your second edit (based on you edit history) looked to me to be trying to cover up vandalism. Your first edit was suspicious at best. -- Kheider (talk) 16:05, 19 February 2011 (UTC)[reply]
I have edited the page to mention 2011 AG5. But with a last observation of 2011-02-15 and closest approach on 26-Feb, I will be curious to see if a larger observation arc removes it from the list. -- Kheider (talk) 16:05, 19 February 2011 (UTC)[reply]

Data misinterpreted: "VK184 is expected to make a close approach to the Earth at a distance of about 0.76 Earth radii (4880km) in 2048."

[edit]

Going to reference #3, distance is "The minimum distance on the target plane (scaled b-plane) from the LOV to the geocenter, measured in Earth radii. For these purposes the radius of the Earth, 6420 km, includes some allowance for the thickness of the atmosphere." For more info, click on the "Introduction" link in reference #3. This is not the minimimum distance from the asteroid to Earth's surface or geocenter.

The first clue to this error is that reference #3 says it will pass within distances of 0.76, 0.46, 0.63, and 0.63 Earth radii in 2048, 2053, 2055, 2057. But what are the odds that in a 9-year span, a single asteroid will pass within an Earth radii of Earth 4 separate times?

Running the numbers obtained from JPL Horizons (the ephemeris, not the online Java orbit visualization applet) shows that the nominal trajectory of 2007 VK184 has it making a close pass to Earth on May 30 2048, at 0.045 AU, or nearly 18 times the distance to the Moon. The online Java applet shows it making a close passage of about 180,000 km on June 2, but they warn not to use this 2-body version if high accuracy is desired. I'll let someone more experienced edit the page. -- 71.131.176.195 on 02:10, 8 August 2011

Thank you for pointing that out. It got left in after someone removed some references from the article. -- Kheider (talk) 03:07, 8 August 2011 (UTC)[reply]

Energy if impact?

[edit]

What would be the megaton equivalent of impact with Earth? Fig (talk) 12:53, 20 February 2013 (UTC)[reply]
