The name was not derived from a famous candy bar. Rather the candy bar was named after the galaxy the Milky Way

A fun way to remember this is to think of the saying: 'Mother’s vegetables every Monday, just sun Pluto'. It doesn’t make much sense but the first letter of each word in this sentence will give you a hint of the name of the planet. The word 'sun' gives you three planets in a row

The planets travel in a rather oval shape or in an elliptical orbit

For decades this was known as the ninth planet from the sun. Scientists now debate whether or not it really is a planet at all. To most, Pluto will always remain the ninth planet, although we now refer to it as a 'dwarf' planet

The two planets similar in size, surface composition, and atmosphere with a complex weather system are often referred to as twins. This planet is often the brightest seen in the night sky. We are talking about Venus. Venus is, however, closer to the sun and her surface temperature can get as high as 470°C. This makes it clearly uninhabitable for man

Asteroids are minor planetoids or celestial bodies that orbit the Sun. Comets are small icy bodies. Cosmic dust is a substance made up of small grains of materials and aggregates. Meteors are small and large rocks that travel through space and can enter the Earth’s atmosphere

The red spot is a huge, long-lasting storm that has been raging on Jupiter for at least 400 years. The spot is now shrinking and will continue to shrink until at least the year 2040. From then, much uncertainty still exists
|
Meteors are large rocks that travel through space. Once a portion of a meteor enters into the Earth’s atmosphere it begins to burn up, decreasing the size of the meteor. By the time the remains reach the Earth’s surface, they are smaller and are referred to as meteorites

One of the most famous ones we know of is named Halley. Of course, we are talking about comets

The study of the stars and celestial bodies (Sun, moons, planets, nebulae, galaxies, etc.) is known as astronomy. The other sciences are more specifically oriented
