Is Oumuamua Artificial? 1I/2017 U1 Update for 12/12/17

TL;DR

There is a small possibility that the interstellar object Oumuamua could be artificial in nature, though it is overwhelmingly likely to be an asteroid.

This is an update in my continuing coverage of the increasingly mysterious object 1I/2017 U1, or Oumuamua, the first observed interstellar object to pass through our solar system. For the backstory, check out my other videos on this channel on the subject, links in the description below and in the end screen. This story has gone into very different... Read More

Key Insights

• 🧑‍🔬 Oumuamua is a highly unusual object that has left scientists with more questions than answers.
• 🛰️ The elongated shape and solid composition of Oumuamua suggest that it may be artificial, although this is not the most likely explanation.
• 🚄 The object's tumbling motion and high speed of rotation are puzzling, and its behavior is not consistent with typical natural objects in space.
• 😚 Oumuamua's close proximity to Earth is noteworthy, but it is likely just a coincidence rather than an intentional observation or visit.

Questions & Answers

Q: Why is Breakthrough Listen pointing the Green Bank radio telescope towards Oumuamua?

Breakthrough Listen is investigating the object for any signs of artificial emissions, although it is highly unlikely to find any.

Q: How does Oumuamua's shape contribute to the idea of it being artificial?

The elongated shape of Oumuamua, possibly 10 to 1 longer than it is wide, could be ideal for minimizing erosion from dust in the interstellar medium if it were an interstellar spacecraft.

Q: Why is Oumuamua's composition unusual for an asteroid?

Unlike most asteroids, Oumuamua appears to be highly solid, potentially made of solid rock or metal. This composition is unusual but not impossible.

Q: Could Oumuamua have been intentionally directed away from Earth?

There is a possibility that Oumuamua, if it is a damaged spacecraft, deliberately avoided a closer approach to Earth to prevent a collision, which could suggest a conscientious decision by any potential extraterrestrial civilization.

Summary & Key Takeaways

• Oumuamua is an interstellar object, likely originating from another star system, that is passing through our solar system.

• It is not a comet but rather an unusually solid asteroid, unlike any known object in our solar system.

• The object is elongated and tumbling, suggesting a potentially artificial origin.
