Wie erkläre ich Kindern was eine Sternschnuppe ist?
Ein Meteoroid stürzt mit rasender Geschwindigkeit auf die Erde. Tritt dieses Teilchen in die Erdatmosphäre ein, trifft es auf Luftmoleküle und drückt diese zusammen. Diese zusammengedrückte Luft wird sehr, sehr heiß – so heiß, dass das Trümmerteilchen in der erhitzen Luft verglüht. Es hinterlässt eine leuchtende Spur.
What is the difference between a meteor and a meteorite?
Think of them as “space rocks.“ When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite. Go farther. Explore Meteors and Meteorites In Depth ›
