If a comet were so large that its mass generated more gravity than what we typically associate with comets, several potential scenarios could unfold depending on its size and mass:
1. **Gravitational Influence**: If a comet reached a mass comparable to that of a small planet (such as Pluto), its gravitational pull would be significant enough to affect not only itself but also nearby celestial bodies. This could lead to gravitational interactions that might alter the orbits of nearby asteroids or even planets if it were in close proximity.
2. **Formation of a Cometary Atmosphere**: A sufficiently massive comet could develop its own atmosphere, similar to what we see with larger bodies like planets or moons. This would occur if the comet's gravity was strong enough to hold onto gases and ices that are typically released as the comet gets closer to the Sun and starts to heat up.
3. **Nuclear Fusion**: If the mass were extraordinarily high (comparable to stellar masses), the conditions could become ripe for nuclear fusion, leading to the formation of a small star rather than a comet. This is not typical for any known cometary body, as they are composed mostly of ice and dust.
4. **Changes in Composition**: A large comet could attract more material to itself due to its increased gravity, potentially altering its composition and structure over time.
5. **Impact Events**: If such a massive comet were on a collision course with a planet, the potential for impact would pose catastrophic consequences, depending on its velocity, size, and the target planet’s environment.
Overall, the existence of a comet with significant mass and gravitational influence would challenge our current understanding of what constitutes a comet and could lead to a range of dynamic and astrophysically interesting phenomena.
