CHICAGO (WBBM NEWSRADIO) -- A researcher who will soon head to Chicago said he thinks he knows what was seen in our solar system in 2017, and it’s not an alien spaceship, as some suggested.

The object with odd movements passed by Earth and did not have a tail like a comet, but it appeared to be speeding up, at times.

It was named “oumuamua” – Hawaiian for “messenger from afar arriving first.”

Darryl Seligman, an incoming postdoctoral fellow at University of Chicago said his research has determined that it is an iceberg of molecular hydrogen.

So, could something like this be dangerous to Earth?

"There's a much lower chance of an interstellar hydrogen iceberg hitting Earth, than Earth being hit by a regular solar system comet or asteroid. The good thing is, is that if there was an interstellar hydrogen iceberg coming closer to Earth, we would detect it in the exact same way we detect hazardous objects that we are constantly monitoring the sky for."

Seligman said Oumuamua’s composition as molecular hydrogen ice signifies the first of a completely new class of astrophysical objects and his paper is being published in Astrophysical Journal Letters.
