Thereâs a frozen, interstellar object about half a mile long whizzing through our solar system right now, and nobody has had a particularly clear idea about what it is â until now. According to a
study published Tuesday in the
Journal of Geophysical Research, it could be a chunk of a Pluto-like planet from another solar system.
It s called âOumuaumua, a Hawaiian word meaning âscoutâ or âmessenger from afarâ in honor of its sighting from the HaleakalÄ Observatory in Hawaii. The strangely shaped interloper may have once been a piece of a solid nitrogen exoplanet that was sent careening in our direction after an impact roughly 500 million years ago. This new theory is one of the most compelling to come out since âOumuamuaâs presence was

Interstellar object ʻOumuamua may be a fragment of Pluto-like planet
The first observed interstellar object zipped through our solar system in October 2017 and astronomers have been trying to understand it ever since.
Scientists scrambled to observe the object before it disappeared, moving along at 196,000 miles per hour, and their observations caused more questions than answers about the “oddball,” as scientists dubbed it.
Now, the latest research suggests it is a fragment of a Pluto-like planet from another solar system.
Steven Desch and Alan Jackson, two astrophysicists at Arizona State University’s School of Earth and Space Exploration, have studied observations made of the unusual features of ‘Oumuamua. Their findings published Tuesday in twostudies in the American Geophysical Union Journal of Geophysical Research: Planets.
