Sun Light takes 500 seconds (8 minutes 19 seconds) to reach from the surface of the sun to the surface of the Earth.

Moonlight takes about 1.3 seconds to reach the earth's surface.

The time taken to complete one revolution of Earth around the Sun is called A year.

Explanation

• Earth is the biggest of all the terrestrial planets.
• It has temperature, weather, atmosphere and many other factors.
• Its surface 30% is covered with land and 70% with water.
• It has only one moon called Luna.

This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two, and only on the night of a full moon.

Explanation

• Asteroids are irregularly shaped solid objects composed primarily of rocks and metals.
• They are found mainly in the asteroid belt between Mars and Jupiter.

Explanation

• Terrestrial planets are small, rocky planets that orbit close to the Sun, and include Mercury, Venus, Earth, and Mars.
• They are composed primarily of silicate rocks and metals, and have surfaces that are heavily cratered.
