SOLAR SYSTEM FORMATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Our Sun formed, like any other star, from ____
A
a collision between two massive planetary objects
B
empty space
C
a black hole
D
the collapse of a cloud of matter under the pressure of gravity
Explanation: 

Detailed explanation-1: -Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as “stellar nurseries” or “star-forming regions", collapse and form stars.

Detailed explanation-2: -Star-Forming Nebula Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots.

Detailed explanation-3: -As gravity compresses the core of a protostar, the temperature goes higher and higher. Eventually the temperature is high enough that the star starts fusing hydrogen into helium. When the outward pressure produced by the heating of the gas by fusion energy balances gravity, a stable star is formed.

Detailed explanation-4: -Gravity constantly works to try and cause the star to collapse. The star’s core, however is very hot which creates pressure within the gas. This pressure counteracts the force of gravity, putting the star into what is called hydrostatic equilibrium.
