What if Venus and Neptune switched places?
The suffocating greenhouse effect that exists there today would disappear. Much of its atmosphere would become solid since it is composed mostly of carbon dioxide, which solidifies at -56.57 degrees Celsius, and the planet’s temperature would now be -148 degrees Celsius.
What would happen if Mars replaced earth?
If Mars were to become our only natural satellite, things in this part of the Solar System would change. For Mars, taking the place of the Moon would mean temperatures on the red planet would rise from their current average of -60°C (-80°F). Its polar ice cap would melt.
Did you know these 10 interesting facts about Neptune?
DID YOU KNOW? 1 • A day on Neptune is 16 hours, but a year lasts 165 Earth years. Barely one Neptune year has passed since the planet’s… 2 • Neptune has six rings and 13 confirmed moons. One of these moons, Triton, has geysers that spray icy material more… 3 • Neptune’s magnetic field is 27 times mightier than Earth’s. More
What makes Neptune different from other planets?
Like Jupiter and Saturn, Neptune is a gas giant—a big ball of gas surrounding an Earth-size core of hot liquids rather than rocks or other solid matter. And like fellow “ice giant” Uranus, Neptune’s atmosphere is composed mostly of water, ammonia, and methane. It’s the methane that gives Neptune its striking blue hue.
How long is a day and year on Neptune?
DID YOU KNOW? • A day on Neptune is 16 hours, but a year lasts 165 Earth years. Barely one Neptune year has passed since the planet’s discovery in 1846. • Neptune has six rings and 13 confirmed moons.
What makes Neptune’s atmosphere blue?
It’s the methane that gives Neptune its striking blue hue. You’ll want to keep your ship soaring high in the planet’s atmosphere, which extends down to crushing depths and is home to the windiest weather in the solar system. Clouds of frozen methane whoosh as fast as a fighter jet through storms the size of Earth.
