Can stars be destroyed?
A supernova does not completely destroy a star.
Supernovae are the most violent explosions in the universe.
But they do not explode like a bomb explodes, blowing away every bit of the original bomb.
Rather, when a star explodes into a supernova, its core survives..
What are 3 characteristics of gas giants?
Unlike terrestrial planets whose composition is rocky, gas giants have a mostly gaseous composition, such as hydrogen and helium. They do have some rocky material, although this is most often found in the planet core. The four gas giants are (in order of distance from the Sun): Jupiter, Saturn, Uranus, and Neptune.
Could the Death Star destroy a gas giant?
Yes. You could destroy a gas-giant, but it wouldn’t be a good idea. You’d probably cause a fusion reaction, making a small star.
What happens if you fall into a gas giant?
This is a lot faster than you’d fall from the top of Earth’s atmosphere because Jupiter’s gravity is much stronger than Earth’s. You’ll still be able to see the sun, but don’t expect it to heat you up. At about 250 km (155 miles) down you’d reach the ammonia clouds and experience -150 C (-240 F) temperatures.
Is it possible to destroy a planet?
With a pure antimatter bomb, the Death Star wouldn’t have to supply all the energy needed to blow Alderaan to smithereens—only half (about 1.24-trillion tons). … So, it’s perfectly reasonably that a tiny amount of matter (or, in this case, antimatter) could destroy an entire planet.
Can Star Destroyers destroy stars?
No, as far as we know, the current Empire lacks the ability to easily destroy stars. A star destroyer is just a name. … The size of stars means they are simply too large to be affected by the Empire’s weaponry.
Is Pluto a gas giant?
So inconspicuous that it was not discovered until 1930, Pluto is not a gas giant planet like all the others in the outer solar system. Instead it is a small, rocky world about the size of Earth’s Moon. Recent examinations of old photographs, combined with new observations, indicate that Pluto itself has a moon.
Why have the gas giants failed to collapse into stars?
Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. … The gas giants’ cores are thought to consist of heavier elements at such high temperatures (20,000 K) and pressures that their properties are poorly understood.
Is Jupiter a failed star?
“Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
What is the smallest gas giant?
NeptuneRadius, diameter, and circumference Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers).
Can you walk on a gas giant?
Unlike rocky planets, which have a clearly defined difference between atmosphere and surface, gas giants do not have a well-defined surface; their atmospheres simply become gradually denser toward the core, perhaps with liquid or liquid-like states in between. One cannot “land on” such planets in the traditional sense.
What planet is the windiest?
NeptuneNeptune is our solar system’s windiest world. Winds whip clouds of frozen methane across the planet at speeds of more than 2,000 km/h (1,200 mph)—close to the top speed of a U.S. Navy F/A-18 Hornet fighter jet.
Can gas giants become stars?
If a large cloud of interstellar gas came Jupiter’s way, maybe the planet could gain enough extra mass to start fusion. … If it accreted even more mass, just enough to become a true star, it would be a dim red dwarf.
How do gas giants stay together?
It has mass and posses gravity just like solid matter does. … So much gas that it has mass 2 and a half times the mass of all the other planets combined. So much mass means it has got tremendous amount of gravity. And it is this gravity that is holding all the gases together.
What are the 4 gas giants?
The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter.
