A mysterious object will fly above the earth in the next month (February 2017). His features are so unusual that researchers at NASA failed to find out what it is, according IFL Science.

The object was named WF9 2016 was observed in NEOWISE project of NASA, on November 27, 2016. Researchers say it may have at least one kilometers wide. Most will approach Earth on February 25, reaching a distance of 51 million kilometers.

The object caused confusion among researchers at NASA, because they do not know whether it is an asteroid or a comet. In general, asteroids are more rocky and metallic, while comets have ice in their composition, their notes IFL Science.

,, 2016 WF9 could be a comet. This article illustrates that the boundary between asteroid and comet is very small, '' James Bauer supports NASA.
