What do we know about the dimensions and the origin of the Oumuamua object? A) It is several miles across; it originated from inside the Solar System (akin to an asteroid) B) It is several miles across; it originated from outside the Solar System C) It is a few hundred feet across; it originated from inside the Solar System D) It is a few hundred feet across; it originated from outside the Solar System
The correct answer is B) It is several miles across; it originated from outside the Solar System.
To know this, you can refer to the available scientific literature and articles published by researchers and astronomers. Oumuamua is the first known interstellar object detected passing through our Solar System. It was discovered in October 2017 and has been extensively studied since then.
The dimensions of Oumuamua have been estimated based on various observations. Scientists believe that it is several miles (or kilometers) in length, making it quite elongated compared to typical asteroids or comets. The exact dimensions are uncertain because Oumuamua does not emit visible light, and its shape has been inferred based on the changes in its brightness as it rotates.
Regarding its origin, extensive analysis of Oumuamua's trajectory, speed, and other characteristics has led scientists to conclude that it originated from outside our Solar System. Based on its speed and the gravitational interaction it experienced while passing through our Solar System, researchers determined that it could not have originated from within our Sun's gravitational influence.
Therefore, the correct answer is B) It is several miles across; it originated from outside the Solar System.
