There are more than 30,000 Earth-grazers (asteroids that can collide with Earth) known
Did you know that as of 2024, there are over 30,000 known so-called Earth-grazers (NEOs or Near Earth Objects)? Earth-grazers are asteroids whose orbits intersect with that of Earth. In the future, these Earth-grazers could...
The tides (high and low water) are largely caused by the Moon
Did you know that the tides, or ebb and flow, are caused by the Moon? The Moon's gravitational pull is so strong that it causes the water in the seas and oceans to be pulled up by several meters. This is called high tide, which...
The Sun is almost 110 times larger than the Earth
Did you know that the diameter of the Sun is almost 110 times greater than the diameter of the Earth? The diameter of the Sun is nearly 1.4 million km (1,400,000 km). The diameter of the Earth is almost 13,000 km. The Earth is...
Sunlight takes just over 8 minutes to travel from the Sun to the Earth
Did you know that a ray of sunlight takes over 8 minutes to travel from the Sun to Earth? The Earth is on average 150 million (150,000,000) km away from the Sun. A ray of sunlight (or light, in general) travels at the speed of...
There are more than 200 moons in the Solar System
Did you know that there are more than 200 moons and candidate moons in the Solar System? The Earth has only 1 moon. The planet Jupiter, however, has 90 moons. When a large object orbiting a planet is discovered, a procedure is...
A person weighing 75 kg on Earth weighs just under 13 kg on the Moon
Did you know that a person weighing 75 kg on Earth weighs just under 13 kg on the Moon? On Earth, a person weighing 75 kg would weigh only about 13 kg on the Moon. This difference is due to the Moon's much weaker gravity...

Did you know that over 5000 exoplanets have already been discovered? Exoplanets are planets outside our solar system. These exoplanets cannot be seen "normally" with a telescope but are discovered using special techniques. For...
Enormous clouds of alcohol in the universe
Did you know that enormous clouds of alcohol have been discovered in the universe? Even in our own Milky Way, these alcohol clouds have been found. These clouds are sometimes more than 1000 times larger than the distance from...
The Milky Way is visible to the naked eye
Did you know that, during a clear night, you can see our galaxy, the Milky Way, with the naked eye? The Milky Way is a spiral with several arms. Our Solar System is located in one of the arms (the Orion arm) on the outer edge of...
