Kāpua is a 500.025±0.025 kilometer sized interstellar object composed of porous rock that passed by planet Roblox. It broke the record for the closest interstellar object to Roblox but not colliding to the planet.
Astronomical Synopsis
On April 9th, 2003, Mr. Bloxington Harry Smith was working at Jarison, when he discovers an interstellar object moving 200 kilometers per hour. He took a picture of it and sent the picture on Bloxbook, where it got very popular. It is very weird shaped, resembling a vertical mushroom to some Robloxians too. It was named Kāpua(Cloud), or grandiloquently, Kāpua o kahi hake (Cloud of a hake). He named it after a Hawaiian name because he is born in the island of Bloxwaii who speaks Oofese and Hawaiian, the latter being an Earth language.
He then predicted that the Kāpua would break the record for the closest interstellar object to Roblox but not colliding to it on April 23rd or April 24th.
Turns out, his predictions were spot on, and on April 23rd, the asteroid did break the record for the closest interstellar object to Roblox but not colliding to the planet. It reached perihelion shortly after.
The interstellar object would then undergo a hyperbolic trajectory, which meant it would not come back because it had no aphelion. It returned back to its original distance it was sited on May 8th, 2003.
Despite the fact it had no aphelion, the interstellar object got very popular on Bloxbook, presumably because a user said that the interstellar object might have been responsible for a Roblox-storm in 2002. In 2017, popularity finally waned as Robloxia finally found out that the Roblox-storm was caused by an alien satellite trying to control Robloxia's climate. It continued to wane until January 15, 2019.
