The force of gravity causes a cloud of dust & gas in outerspace to collapse, condense and form a star. All stars form from a (a)   .

Apparent brightness depends on both luminosity and (a)   . While, ​ (b)   brightness is based only on luminosity. The sun has a greater​ (c)   brightness than ​ (d)   brightness because Earth is so close to it.

• distance
• absolute
• apparent
