What is a bright object that gives off light by energy produced in its core?
A
A satellite
B
A star
C
An asteroid
D
A planet
Explanation: 

Detailed explanation-1: -A star is a huge glowing ball of hot gas. Deep inside its core, hydrogen atoms smash together, forming helium and releasing huge amounts of energy that heats the gas. This is called nuclear fusion, and it’s why a star shines.

Detailed explanation-2: -Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space.

Detailed explanation-3: -Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy.

Detailed explanation-4: -What makes stars shine? Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the “proton-proton chain, ‘’ a sequence of events that transforms four hydrogen atoms into one helium atom.

Detailed explanation-5: -A star is an astronomical object comprising a luminous spheroid of plasma held together by self-gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light.
