Can gas giants turn into stars?
Stellification is a theoretical process by which a brown dwarf star or Jovian-class planet is turned into a star, or by which the luminosity of dim stars is greatly magnified.
What happens when two gas giants collide?
The pieces would tend to either fall back down, or remain in orbit around the merged body and coalesce into one or several moons. It is not impossible that some fragments would end up ejected at high speeds and keep moving forever away from the collision, although that’s probably not very typical.
What would happen if Saturn lost its rings?
These areas would appear darker in reflected light, thus creating the appearance of darkened bands in Saturn’s atmosphere. Another outcome would be an increased lifespan in the electrically charged particles known as H3+ ions (which are made up of three protons and two elections).
Can you walk on Saturn rings?
While they look like giant discs, they’re not a solid track at all. Instead, they’re made of millions of chunks of ice, some as tiny as dust particles, others as large as buses. But if you were able to hike on one of Saturn’s outermost rings, you’ll walk about 12 million kilometers to make it around the longest one.
Can you stay on Saturn?
Saturn. This is another space giant that will allow you to stay on it for less than one second. Apart from the gas clouds, Saturn constantly has very strong winds which can reach 1800 km per hour.
What would happen if Earth had rings like Saturn?
Earth’s hypothetical rings would differ in one key way from Saturn’s; they wouldn’t have ice. Earth lies much closer to the sun than Saturn does, so radiation from our star would cause any ice in Earth’s rings to sublime away. Still, even if Earth’s rings were made of rock, that might not mean they would look dark.
Which planet has a day that is longer than its year?
Venus
What is the longest day in the universe?
So, Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days. Its day lasts longer than its orbit. It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.
Which planet has the longest rotation?
Which planet takes the longest time and the shortest time for one rotation?
Jupiter
