Comets are falling rocks, whose paths can be calculated quite precisely.
The singular form is comet, the plural form is comets, the possessive plural is comets'. Example: The comets' paths will not cross.

The experiment that confirmed Halley's hypothesis regarding the nature of comets was conducted by Edmond Halley himself in 1705. He predicted that the Great Comet of 1682 would return in 1758, based on its orbit. When the comet reappeared as predicted, it was named Halley's Comet in his honor, validating his theory that comets could have predictable orbits similar to planets. This observation established the notion that comets are not random but instead follow specific paths through the solar system.
Comets go around the Sun in a highly elliptical orbit.
There are scores of comets who's orbits have been determined, and are predicted to return, but the best known one is probably Comet Halley.
Comets have been seen and studied by people for thousands of years. Edmond Halley predicted a comet to return in 1705 which is why we call it Halley's Comet or Comet Halley.
Niels Bohr, a Danish physicist, proposed the idea that electron paths cannot be precisely predicted. This concept is known as the "Copenhagen interpretation" of quantum mechanics, which suggests that the behavior of particles on a quantum level is inherently probabilistic.
The concept that paths cannot be predicted is often attributed to Edward Lorenz, a meteorologist and mathematician. His work in chaos theory and the famous "butterfly effect" highlighted the sensitivity of certain systems to initial conditions, leading to unpredictable outcomes.
Objects in our solar system, including planets, asteroids, and comets, travel around the Sun in elliptical orbits. The planets orbit the Sun in nearly circular paths along a plane known as the ecliptic. Comets and asteroids can have more eccentric and tilted orbits compared to the planets.
Comets do not fall. They orbit around the Sun in elongated orbits, with their paths often bringing them close to the Sun before they swing back out into the farther reaches of the solar system. This motion is due to the gravitational forces acting on the comet from the Sun.

There are currently no known asteroids predicted to hit the Earth in the near future. Scientists continuously monitor asteroids and comets that come close to Earth, and there are no imminent threats at this time.
