• To explore other planets in the solar system

• To study the Earth's climate, oceans, land, and climate change

• To search for extraterrestrial life

• To monitor space debris

Earth's Satellites

Trivia: Satellites orbiting the Earth serve various purposes. They study the Earth's climate, oceans, land, and climate change. They also monitor space debris to ensure the safety of other satellites. However, their main purpose is to study and understand our own planet. They provide valuable data for scientific research and help us make informed decisions about our environment.

Exploring Our Planet: Earth

• Earth is the third planet from the Sun in our solar system. Our closest neighbors are Venus and Mars. • Earth has only one moon. • Earth has many satellites that observe and study it. There is still much to learn about our planet. • A day on Earth lasts just under 24 hours. • A year on Earth lasts 365.25 days, which is why we have a leap year every 4 years.
