Document Summary
The solar was formed by a cloud of gas and dust in space that was disturbed by a supernova. The nebular hypothesis: the explosion made waves in space forming a solar nebula. Solar nebula: flattened cloud of gas and dust. The center of the solar nebula grew hotter resulting in the formation of the sun. The outer edges cooled causing clumps of particles to stick together and form planets. The solar system is composed of 8 planets, 60 moons and millions of bolides. Order of the planets: mercury, venus, earth, mars, jupiter, saturn, uranus, neptune. Galaxy: a cluster of billions of stars, our solar system is a tiny wave of the milky way galaxy. Star: a hot glowing ball of gas that generates energy by converting hydrogen to helium. 30 quintillion km from the center of the milky way. It takes nearly 100 000 years to travel from one side of the galaxy to the other.
