Planetary temperatures are effected by the sun, and the biggest contributing factor to a planet's average temperature is its proximity to the sun. Because of this, the inner planets are solid, either rock based, metal or a combination of both, and all have higher average temperatures than the outer planets. As the farthest planet from the sun, Neptune receives little to no warmth from solar rays. There are five dwarf planets in our solar system, including Pluto, and they are Ceres, Makemake, Haumea and Eris. Because, as we know from our daily lives down here on planet Earth, temperatures vary greatly depending on geographical location and time of year. Given that we expect planets further from the Sun to be colder than those closer, this does make Neptune and … Mercury, the Solar System's hottest planet. The first four, known as the inner planets, are terrestrial bodies. As the graphic shows, the range of temperatures within our own solar system is very large. As they orbit the Sun, planets are sometimes closer and sometimes farthest from the Sun. After all, most of us learn to name the planets in order, beginning with the one closest to the sun and ending with the one farthest from it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Premature Aging In Cancer Survivors: Why It Happens And What To Do About It! Neptune is so far from the sun, at a distance of roughly 2.8 billion miles, that it is the only planet which cannot be seen with the human eye alone. ISSN: 2639-1538 (online), Otter Trawl Gear Effects On Estuary Ecosystems, More Worried Than Before: Parents Describe Growing Concern Over Their Kids’ Weight, Exercise Fluid Balance – Pints Vs. Temperatures on the planets depend on the sun and other factors. Also, there is a big difference between summer and winter temperatures in New York. So life is probably quite prevalent. This means they are rock and metal based planets. Image credit: Vadim Sadovski/Shutterstock.com. Australian […], Throughout the history of homo sapiens, there has been an intense focus and investment on alleviating the signs and symptoms […], Asthma is the result of a complex and dysregulated immune response in which the bronchial airways become inflamed and constricted. With Uranus at an average distance of 2.88 billion kilometres from the Sun and Neptune at an average distance of 4.5 billion kilometres it would be very easy to point out which of the gas giants is the coldest, but if you were you were to say that Neptune was the coldest, you’d be wrong. Metagenomics […], The stable isotopes of hydrogen (δ2H) and oxygen (δ18O) have been widely applied in hydrology. Pluto, at one point considered the smallest and farthest planet in our solar system, was officially demoted from planetary status in 2006. At an average temperature of minus 20 degrees Fahrenheit, it is the closest to the Earth’s temperature. We're sorry to hear that! Both Neptune and its neighbor, Uranus, are basically balls of rock, ice crystals (methane), ammonia, and water. For someone who has endured a US Midwest winter, it might not seem possible that coldest temperatures could exist. It is true that, in fact, Neptune is, on average, colder than Uranus. After all, once you have removed poor Pluto from the equation, then Neptune becomes the farthest planet from the Sun. The coldest planet in the solar system is Neptune with an average temperature of -353 degrees Fahrenheit or -214 degrees Celsius.

It was only during the late 1980s, that astronomers were able to discover its various characteristics for the first time ever with the help of Hubble and Voyager 2. When the universe was young, these would have been the only planetary bodies that would have been able to withstand the heat of the young star. Atmospheric conditions are also key to understanding planetary temperatures. “I can remember at the age of about six being fascinated by the planets and learning all about Mars and Venus and things.” — Richard Dawkins. Neptune is the farthest planet from the Sun in our solar system. The first thing to note about distance is that it is not always the same. We cover everything from solar power cell technology to climate change to cancer research.
