Who discovered the first planet?
Brian says that when Galileo put his telescope on Jupiter, he saw four tiny dots moving around the gas giant. “They were all in line with the equator of Jupiter they all moved round… in a regular manner.” This showed Galileo something extremely important – that the planets could orbit things other than Earth.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya. He studied in Athens at the Lyceum.

What is the oldest planet?
Jupiter formed in a geologic blink. Its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported Monday in the Proceedings of the National Academy of Sciences.
How cold is space?
Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops. But this temperature is not constant throughout the solar system.
What’s Earth’s twin planet?
Venus
Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
