The object is an asteroid called 2016 HO3 and orbits our planet in an elongated orbit. From the video the orbit looks to be perpendicular to the solar plane, but to my eyes it is hard to tell for sure.
It is believed that 2016 H03 has been orbiting the earth for only about 100 years.
The URL shows a short video of the asteroid and its orbit.

As it turns out, with a radio relay system setup, these proximity keyfobs make entering and stealing vehicles relatively easy. Researchers at ETH Zurich were able to beat the keyfob systems from 8 different manufacturers. In one possible scenario, crook number one follows a car owner into a store. Standing a few aisles away, he picks up the signal given off by the victims keyfob, transmitting it to crook number two, who is near the victim's car. Crook number two relays the signal to the car, which then unlocks. With push button startup, it's then a snap to drive away.

The article offers possible explanations for a few trends, such as the Civil War's influence on the popularity of presidential beards, beards being considered virile and militaristic I assume. Mustaches followed until the invention of the safety razor. For the past 100 years, the hair styles have remained almost the same.
One trend noticeable to me is the appearance of conforming news-anchorman style haircuts starting from the time of televisions widespread adoption.
What is the cause of the recent conformity? Is it the rise of media technology? Is it possible for someone with facial hair or a queue to be elected today?
