Answer:
Th similarities between the black hole and the neutron star is that they are formed from dead (dying) starts. But they come from different parent stars, if the parent star is 1.4 times the mass of the sun, a neutron star will be formed, but if the parent star is twice the mass of the sun a black hole is formed.
Explanation:
A black hole is defined as an area of space whereby the matter is so compacted that nothing can escape from it. This area is called <em>event horizon. </em>Black holes are formed when an enormous star dies in z supernova. They weigh at least twice the sun's mass, and their mass is directly proportional to their radii.
Neutron stars are created during supernova and maintained by a neutron called <em>degeneracy pressure.</em> Neutron star has a small radius, typically 30 km, with a very high density made up of compacted neutrons.

Explanation:
Alexander the Great was a king of Macedonia who conquered an empire that stretched from the Balkans to modern-day Pakistan. Alexander was the son of Philip II and Olympias (one of Philip's seven or eight wives). He was brought up with the belief that he was of divine birth. He became king upon his father's death in 336 BCE and went on to conquer most of the known world of his day. He is known as 'the great' both for his military genius and his diplomatic skills in handling the various populaces of the regions he conquered.
During Hadean time, the solar system was forming within a cloud of dust and gas known as the solar nebula, which eventually spawned asteroids, comets, moons and planets. Astrogeophysicists theorize that about 4.52 billion years ago the proto-Earth collided with a Mars-size planetoid named Theia.
