* Vastness of Space: Space is incredibly vast, and the chances of a large object like a comet colliding with Earth are very slim.
* Constant Monitoring: Astronomers are constantly monitoring the skies for potential threats, like asteroids and comets.
* Deflection Technology: We are developing technology that could potentially deflect an object on a collision course with Earth.
While the risk is low, it's not zero. Astronomers track and monitor objects that could pose a threat, and we have procedures in place to respond if a serious risk emerges.
To answer your question directly, there is no known comet currently on a trajectory to hit Earth.
