Answer 1

1. A star is a giant ball of very hot gas, mainly hydrogen and helium. It is held together by a force called gravity.2. Stars go through a process called nuclear fusion.3. Stars in the sky differ in size and temperature.4. A constellation is a group of visible stars that form a pattern when viewed from Earth.5. The stars we see in a constellation are very far from us.6. Constellations appear to move, but that is only because the Earth rotates.7. Scientists divided the sky into 88 different constellations.

Answer 2

## Step 1The first part of the question asks for the definition of a star. A star is a celestial body that is primarily composed of hydrogen and helium. The force that holds a star together is gravity.## Step 2The second part of the question asks about the process that stars undergo. This process is known as nuclear fusion, where hydrogen atoms combine to form helium, releasing a large amount of energy.## Step 3The third part of the question asks about the characteristics of stars in the sky. Stars in the sky differ in size and temperature.## Step 4The fourth part of the question asks for the definition of a constellation. A constellation is a group of visible stars that form a pattern when viewed from Earth.## Step 5The fifth part of the question asks about the distance of stars from Earth. The stars we see in a constellation are very far from us.## Step 6The sixth part of the question asks about the apparent movement of constellations. Constellations appear to move, but this is only because the Earth rotates.## Step 7The seventh part of the question asks about the number of constellations. Scientists have divided the sky into 88 different constellations.
