In a year, a mystery of science called the Millennium Falcon will fly to Earth.
The Comet 12P/Pons-Brooks description in your question seems to be a hypothetical scenario created for storytelling purposes; as of my last knowledge update in September 2021, no such event has been reported. However, I can provide some general information about comets and their behavior.
Comets are celestial bodies of ice, dust, and other organic compounds. They originate from the solar system’s outer regions, such as the Kuiper Belt and the Oort Cloud. When a comet gets closer to the Sun during its orbit, solar radiation heats the ice, causing it to vaporize and release gas and dust into space, forming a bright coma around the comet’s nucleus.
Comets can exhibit different shapes and brightness levels depending on the amount of gas and dust released and the angle at which they are observed from Earth. Occasionally, comets may experience outbursts, causing a sudden increase in their brightness, but the exact mechanisms behind these outbursts are not always well understood.
Regarding the transfer of liquid water by comets, it is a hypothesis that comets could potentially carry water from their interiors. Water is believed to be present in comets in the form of ice, and it has been suggested that comets could have played a role in delivering water to Earth and other bodies in the early solar system. This is significant because water is essential for developing life as we know it.
When a comet gets closer to the Sun, the solar heat can cause the ice to sublimate, creating a coma of gas and dust around the nucleus and forming a tail that points away from the Sun due to solar wind and radiation pressure.
If astronomers were to observe a comet that suddenly changed its shape or exhibited unusual behavior, it would attract much attention from the scientific community. They would likely focus on keeping the comet’s properties, gathering data on its composition, and studying its behavior to understand the underlying mechanisms causing the changes.
As for the comet’s close approach to the Sun happening shortly after a total solar eclipse, this would be a fascinating astronomical event. Still, the specific effects of such a coincidence would depend on the comet’s size, composition, and distance from Earth.
Remember that the scenario you described appears to be a fictional narrative. While comets can be mysterious and present unexpected phenomena, astronomers would need actual observations and data to draw accurate conclusions about the behavior of a specific comet-like 12P/Pons-Brooks.
