Listed following are several astronomical objects. Rank these objects based on their diameter, from largest to smallest. (Note that the neutron star and black hole in this example have the same mass to make your comparison easier, but we generally expect black holes to have greater masses than neutron stars.)1. main-sequence star of spectral type a2. jupiter3. a one solar mass white dwarf4. the moon5. a two solar mass neutron star6. event horizon of a two solar mass black hole

1. Main-sequence star of spectral type A

2. Jupiter

3. A one-solar-mass white dwarf

4. The Moon

5. A two-solar-mass neutron star

6. The event horizon of a two-solar-mass black hole.

Explanation:

This astronomical objects are ranked is based on their diameter and they are ranked from the largest diameter to the smallest diameter.

Main-sequence star of spectral type A has the largest diameter.

While the event horizon of a two-solar-mass black hole has the smallest diameter.

the answer is the last option or letter d)
