Which statements are true about stars smaller than the sun? They have longer lifespans. They consume their hydrogen fuel slowly. They use helium, not hydrogen, as fuel. They are more luminous than the sun.

The answer is "They have longer lifespans" and "They consume their hydrogen fuel slowly"

Explanation:

A star is a galactic item comprising of luminous spheroid of plasma held together by its own gravity. The closest star to Earth is the Sun. Numerous different stars are obvious to the unaided eye from Earth during the night, showing up as a large number of fixed radiant focuses in the sky because of their gigantic separation from Earth.

For the vast majority of its dynamic life, a star sparkles because of atomic combination of hydrogen into helium in its center, delivering energy that navigates the star's inside and afterward transmits into space. Practically all normally happening components heavier than helium are made by heavenly nucleo-synthesis during the star's lifetime, and for certain stars by supernova nucleo-synthesis when it detonates. Close to the furthest limit of its life, a star can likewise contain degenerate issue

A star's life starts with the gravitational breakdown of a vaporous cloud of material made essentially out of hydrogen, alongside helium and follow measures of heavier components. At the point when the heavenly center is adequately thick, hydrogen turns out to be consistently changed over into helium through nuclear fusion, producing energy all the while.
