Solar Radiation: How Sunlight Heats the Planet
Our sun is 99% of the total mass of the solar system. It’s this energy from the sun’s thermonuclear reactions that heats the Earth from solar radiation.

Main Sequence Star: Our Sun’s Thermonuclear Reaction
Our sun is a main sequence star. This just means that it burns hydrogen into helium and goes through this “main sequence” for about 95% of its life span.
Where is the North and South Pole?
If you stick a pencil through Earth at the point of rotation, these 2 points are the north/south poles. Geographically, it’s where longitude lines converge.
A Guide to Earth’s Lithosphere
Earth scientists compare the lithosphere to a thin, solid and brittle eggshell encasing our inner planet or a thick piece of wood that dries and breaks.
How To Define the Geosphere
It’s difficult to pinpoint an exact definition for the “geosphere” because it’s used in several different ways. But here are 2 ways to define the geosphere.
Earth Statistics: Straight-Up Stats of Earth
This list of Earth statistics provides all the numbers of our home planet. For example, here are size, rotation, density, temperature, orbit, age and more.
How Gravity Sculpted the Earth
What brings order on Earth is gravity. For all matter, it’s always at work. This is how gravity works for ocean tides, planet formation and escape velocity.
What is the Goldilocks Zone?
Lucky for us, Earth is in the Goldilocks zone. The range where liquid water persists is 0.99 to 1.7 AU. But it doesn’t necessarily mean life or water exists.

9 Facts About the Moon [Infographic]
Earth’s moon was formed at the same time that Earth did. Interesting moon facts include its gravity is 1/6 of Earth and temperature range of -173°C to 127°C
How Did the Moon Form?
The giant impact hypothesis models the formation of our moon. It starts with a Mars-sized object hitting Earth. This object (moon) still remains in orbit.
