Which of the following best describes what would happen if a 1.5-solar-mass neutron star,with a diameter of a few kilometers,were suddenly (for unexplained reasons)to appear in your home town?
A)The entire Earth would end up as a thin layer,about 1 cm thick,over the surface of the neutron star.
B)It would rapidly sink to the center of Earth.
C)The combined mass of Earth and the neutron star would cause the neutron star to collapse into a black hole.
D)It would crash into Earth,throwing vast amounts of dust into the atmosphere that,in turn,would cool Earth;this is probably what caused the extinction of the dinosaurs.

BA neutron star has an extremely high density, so if one appeared in your hometown, its gravitational pull would be immense, drawing in the Earth's material. This would result in the Earth being compacted into a thin layer over the neutron star's surface. Additionally, due to its massive density and small size, it would likely sink towards the center of the Earth due to gravitational attraction, affecting the planet's structure and dynamics on its way down.
