'Oumuamua: The Cosmic Wanderer Hoodie

'Oumuamua, the first known interstellar object to visit our solar system, was discovered in 2017 by astronomers using the Pan-STARRS 1 telescope in Hawaii. The name 'Oumuamua is Hawaiian for "a messenger from afar arriving first."

Formally designated 1I/2017 U1, 'Oumuamua is a highly elongated object, approximately one-quarter mile (400 meters) long and ten times as long as it is wide, with a reddish hue. Scientists believe it originated from a distant star system and has been traveling through space for millions of years.

What We Know:

• Interstellar Origin: 'Oumuamua's speed and trajectory suggest it came from beyond our solar system, traveling at about 196,000 mph.
• Hyperbolic Trajectory: It will continue its journey out of our solar system, never to return.
• Elongated Shape: Brightness variations indicate it's highly elongated, up to ten times longer than wide.
• Tumbling Motion: The object tumbles through space, rotating around multiple axes.

What We Don't Know:

• Exact Appearance: Specific surface features and overall appearance remain unknown.
• Composition: Its makeup is still a mystery, potentially containing gases like carbon monoxide or carbon dioxide but lacking visible dust.
• Origin: The exact star system 'Oumuamua came from is unknown.
