- Potentially_hazardous_object abstract "A potentially hazardous object (PHO) is a near-Earth asteroid or comet with an orbit such that it has the potential to make close approaches to the Earth and is of a size large enough to cause significant regional damage in the event of impact. A potentially hazardous object with a reasonably well determined orbit can be known not to be a threat to Earth for the next 100 years or more.As of 1 August 2015 NASA had listed a cumulative total of 1,605 discovered potentially hazardous asteroids (PHAs). Among these, there are 154 PHAs believed to be larger than one kilometer in diameter. However a calculated diameter is only a rough estimate, as it is inferred from the object's varying brightness—observed and measured at various times—and the assumed, yet unknown reflectivity of its surface (albedo). Most of the discovered PHAs are Apollo asteroids (1,363) and fewer belong to the group of Aten asteroids (147).Due to several astronomical surveys, the number of known PHAs has increased tenfold since the end of the 1990s (see bar charts below). These surveys have lead to a total number of 12,933 discovered near-Earth Objects, most of them being asteroids and some 85 near-Earth comets (NECs). The Minor Planet Center's website Unusual Minor Planets also publishes detailed statistics for these objects.On 19 August 2015, NASA reported that there was \"no scientific basis\" that the world will end due to a rumored impact of an asteroid near Puerto Rico between 15 and 28 September 2015.".
