What conclusion can be reached Therefore if the sun appears less bright at its limb than at the center?
What conclusion can be reached if the Sun appears less bright at its limb than at the center? (a) Light from the limb is reddened by solar rotation and appears cooler and therefore less intense.
Why can’t you see deeper into the photosphere?
Why can’t you see deeper into the photosphere? The photosphere is blocked by the chromosphere. The upper photosphere blocks the light from the deep photosphere. The deep photosphere does not emit visible wavelengths.
Where are spicules found on the sun quizlet?
In solar physics, a spicule is a dynamic jet of about 500 km diameter in the chromosphere of the Sun. It moves upwards at about 20 km/s from the photosphere.
Does the sun have a hard surface?
The Sun is a huge ball of heated gas with no solid surface. The Sun’s surface is always moving. Sometimes storms bigger than the size of Earth can send gas and energy flowing into space.
What are the 7 layers of the sun?
The Sun is the largest object in our solar system. It is composed of seven layers: three inner layers and four outer layers. The inner layers are the core, the radiative zone and the convection zone, while the outer layers are the photosphere, the chromosphere, the transition region and the corona.
Is Sun a gas or solid?
The Sun is our nearest star. It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter.
Is any of the sun solid?
The sun is not a solid mass. It does not have easily identifiable boundaries like rocky planets like Earth. Instead, the sun is composed of layers made up almost entirely of hydrogen and helium.
What is Sun mainly made by?
The Sun is composed primarily of the chemical elements hydrogen and helium. At this time in the Sun’s life, they account for 74.9% and 23.8% of the mass of the Sun in the photosphere, respectively.
Which star is closest to the sun?
Alpha Centauri A
Does the sun have oxygen?
The sun, like the rest of the universe, is made mostly of hydrogen. There isn’t enough oxygen in the entire solar system to keep the surface of the sun burning through chemical combustion for more than a very short time—probably hours. Instead, the sun’s heat and light comes from thermonuclear fusion.
Will the sun last forever?
The hydrogen fuel at the core will finally be exhausted in five billion years when the Sun will be 67% more luminous than at present. Thereafter the Sun will continue to burn hydrogen in a shell surrounding its core until the luminosity reaches 121% above the present value.
What if Jupiter exploded?
If it exploded, the energy from the explosion would throw the traditional outer and inner solar system planets into a free-for-all, sending the larger gas giants either towards the sun or flinging them out of the solar system altogether.
Can we explode Jupiter?
Jupiter’s atmosphere does not contain oxygen, so combustion is not possible.
Can you go straight through Jupiter?
A Solid Core In the distant future, engineers may be able to build a spacecraft that can withstand the conditions inside a gas giant like Jupiter, but even if they do, the craft won’t be able to fly straight through the planet.
What would have happened if there was no Jupiter?
There would be minor changes in the planets’ orbits about the Sun, but very little else. However, Jupiter does a great job of shepherding and absorbing small objects in the Solar System. With Jupiter gone, the main effect on Earth would be an increase in the rate of impacts from asteroids and other space flotsam.
What will happen if there are no planets?
Earth would be too cold to sustain life. The position of Earth in the Solar System not only affects life, but everything that happens on our planet. That’s because, without any other planets keeping us in check, Earth’s gravity would be severely different. When we say ‘no other planets’ we mean no moons either.
Do planets disappear?
Astronomers discovered a planet 16 years ago called Fomalhaut B. And then it just disappeared. Scientists now believe that it may not have been a planet but a light that was caused by an incredible rare cosmic collision. Normally, those planets outside the solar system are obscured by the light from their stars.
What would happen if Jupiter crashed into Saturn?
The new planet would wobble a bit and then settle down. It would be quite hot, causing it to grow significantly in size. It would appear brighter from Earth, both from the reflection by the greater surface and from its own heat, but it wouldn’t be enough to heat Earth or bombard it with heavy radiation.
What happens if 2 gas giants collide?
The short answers are yes; almost like galaxies colliding; and eventually they could become one body with a ring system (like saturn) or a system of two new large bodies; and some gas would be lost outside the system.
What if Saturn crashed into Earth?
By the time Saturn is at the same distance as the Moon, its tides would be many thousands of times stronger than the Moon’s. Fault lines would rupture, volcanoes would blow their tops, and anything left on the surface of the Earth would be wiped out.
What would happen if Earth and Jupiter collided?
As the Earth is pulled into Jupiter, our planet’s velocity could increase until it reaches 60 km/s (37 mi/s). Our planet is too small and would burn up in the atmosphere before that ever happens. This would have a huge impact on Jupiter, as the Earth’s remains would completely mix into its atmosphere.
What would happen if Earth collided with another planet?
The atmospheres of both planets would be compressed together and glow brightly. It would get so hot that everything on the side of the Earth about to get hit would instantly vaporize. For the rest of the Earth, the ground would become scorching magma. The collision would cause friction between the two planets.
