New evidence suggests that billions of years ago, a star may have passed very close to our solar system. As a result, thousands of smaller celestial bodies in the outer solar system outside Neptune ⁘s orbit were deflected into highly inclined trajectories around the sun. It is possible that some of them were captured by the planets Jupiter and Saturn as moons.

When we think of our solar system, we usually assume that it ends at the outermost known planet, Neptune. ⁘However, several thousand celestial bodies are known to move beyond the orbit of Neptune,⁘ explains Susanne Pfalzner, astrophysicist at Forschungszentrum J⁘lich.

Such a flyby can even explain the orbits of 2008 KV42 and 2011 KT19 ⁘ the two celestial bodies that move in the opposite direction to the planets.

Hi. Since I graduated from college, I've been trying to find cool new interesting things to do. Creating special effects wins as my favorite.

SANTA CRUZ, CALIFORNIA "Dad, did you ever imagine that your formula would become so famous?" I ask the kind-eyed, 91-year-old person next to me on the patio. My dad, Frank Drake, is quiet for a moment. Perhaps he's thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind's hunt for extraterrestrial civilizations.

UFO Hunting, With Harvard Data: Astrophysicist Advocates For Scientific Investigation

Avi Loeb: Two things. In 2017, there was an object — the first one that was identified from outside the solar system that arrived close to Earth — and it didn't look like anything we've seen before. It didn't look like a comet, it didn't behave like an asteroid. Loeb: Yes. And I thought maybe it's artificial in origin. And, in fact, I wrote a book about it, Extraterrestrial, that was published six months ago. And then a month ago, there was a report delivered to Congress saying: there are things in the sky above the U.S. whose nature is not identified.
