A dwarf planet has similar characteristics to a planet, it just simply isn't large enough to be considered a regular planet. Pluto's diameter is only 2370km, less than 1/5 of the diameter of the Earth. Pluto itself is very rocky and cold, having average temperatures of roughly -225 degrees Celsius. It has many icy mountains, with heights rising as high as 3500 metres (similar to the Rockies). The orbital period of Pluto is 248 years, while its rotation period is roughly 6.39 days. Pluto's geology is comprised of mostly frozen nitrogen, water ice, and rock. Its atmosphere consists of nitrogen, methane, and carbon monoxide. Pluto has 5 moons which orbit around it. Pluto is one of the largest bodies that belongs to the Kuiper belt, a disc of rocky, icy, and relatively small bodies that orbit past Neptune. Pluto was disc

After studying in Athens in his youth, he made significant contributions to the fields of math, geography, and astronomy. His friends nick-named him "Pentathlos" (an athlete who competes in 5 different sports), due to his nature of pursuing knowledge in a vast variety of fields. Considering the time, many of Eratosthenes accomplishments were remarkably revolutionary and accurate in their respective areas, and some are even used to this day.      One such lasting impact by Eratosthenes is in mathematics. Eratosthenes proposed the first algorithm for finding prime numbers (numbers whose factors only include 1 and itself). The algorithm is known as "Sieve of Eratosthenes" and can be used to find all prime numbers between 1 and a given number. The algorithm involves the following steps: 1. Go through ev
