JUNO

About:

• Jupiter, a gas giant planet covered in thick red, brown, yellow and white clouds, boasts a diameter of about 89,000 miles (1,43,000 km).
  
  
• Interior models based on Juno data indicated Jupiter has a large "diluted" core representing about 5 to 15 % of the planet's mass comprised rocky and icy material unexpectedly mixed with light elements like hydrogen and helium.
  
  
• Computer models indicated that a head-on collision with a protoplanet - a planet in its formative stages - of roughly 10 Earth masses would have broken apart Jupiter's dense core and mixed light and heavy elements, explaining Juno's findings.
