Question

1. why do comets have tails?

solar wind
jupiters gravity
earths magnetic field
the suns gravity

Explanation:

Comets have tails because when they approach the Sun, solar radiation and solar wind (charged particles from the Sun) push dust and gas away from the comet, forming a tail that points away from the Sun. Jupiter's gravity affects comet orbits, Earth's magnetic field impacts near-Earth space, and the Sun's gravity keeps comets in orbit—none of these form the tail.

Answer:

solar wind
