Potentially hazardous asteroid that zipped past Earth has its own 'moon'

A "potentially hazardous asteroid" that whizzed past Earth earlier this month is so large it has its own "moon".

Potentially Hazardous Asteroids (PHAs) are defined "based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth", says NASA.

"Potentially Hazardous Asteroids (PHAs) are now defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth", NASA said in a statement.

NASA has warned that kilometer-sized asteroids can have catastrophic consequences if they collide with earth.


NASA has confirmed that a "potentially hazardous asteroid" is screeching across space at a speed of nearly 34,000 miles per hour and may intersect the planet's path this weekend.

Because the asteroids' paths often cross our planet's orbit, there is a slim chance they might strike in the future. An asteroid this big in dimension holds the potential to destroy a whole continent, let alone a country or a city. Asteroid PZ39 fits in perfectly in the destructive range with measurement estimated between 440 metres to 990 metres.

Asteroids are believed to have caused the extinction of the dinosaurs millions of years ago, but it bears wondering if the Earth today could be affected in the same manner.

Asteroid alert: Will the colossal space rock hit the planet or will it miss?


The premier space agency has traced an asteroid which will eventually come very close to our planet on February 15, reported the Express UK.

"The threat to any one person from auto accidents, disease, other natural disasters and a variety of other problems is much higher than the threat from NEOs".

Currently, there is no known asteroid that is headed directly for Earth and that includes Asteroid PZ39.

It will pass Mars in June but won't be back past Earth until 2022 - by then it will be even further way - it's next close approach won't be until after 2100.


Fortunately, NASA expects the huge space rock to miss Earth by about 3.6 million miles.
