What is the revolving time around the sun?
250 earth years. its orbit is not close to a perfect circle so sometimes it passes neptune as the 2nd farthest planet from the sun and neptune becomes the farthest. im not sure if that changes the revolving time though.
How are Cepheid variables related to the instability strip?
Cepheid variables are high-mass, pulsating variables exhibiting a regular relationship between the period of pulsation and luminosity. When a star's evolutionary track carries it through a region called the instability strip in the HR diagram, the star becomes unstable and begins to pulsate. These stars are important to astronomers who study galaxies because Cepheids can be seen at extragalactic distances, and their period or pulsation tells us their luminosities, which in turn tells us their distances. - Cincinnati
Composition of the atmosphere of Neptune?
The atmosphere of Neptune is mainly helium and hydrogen, with trace amounts of ammonia, methane and water. Neptune is a gas giant with a small solid core. Neptunes atmospere contains variable gases, ice, and water. Also the center of Neptunes core is made of ice and water also.
Why can't we see the sun's corona under normal conditions?
The corona is not visible under normal conditions because the sun's surface (photosphere) is much brighter than the corona. During a total solar eclipse, when the moon blocks the photosphere, the corona becomes visible to the naked eye.
Just as a low-mass main sequence star runs out of fuel in its core it actually becomes brighter How is this possible?
During this phase, the core contracts and heats up, causing the outer layers of the star to expand and become less dense. This expansion increases the surface area of the star, leading to a higher luminosity. While the core is running out of fuel, the outer layers are still burning hydrogen, which also contributes to the increase in brightness.
How does the diameter and luminosity of a main sequence star change when it becomes a giant or a supergiant?
In that case, both the star's diameter and its luminosity greatly increase.
What planet becomes the farthest from the sun every 248 years?
Neptune
Is the radius of a star increases how do you think it's Luminosity might change?
If the radius of a star increases, its luminosity is likely to increase as well, assuming its temperature remains constant. Luminosity is proportional to the surface area of the star and the fourth power of its temperature, as described by the Stefan-Boltzmann Law. Therefore, even a modest increase in radius can lead to a significant rise in luminosity. If the star also becomes hotter, the luminosity would increase even more dramatically.
What are the surface materials on neptune?
As a gas planet, Neptune does not have a definite surface. It has an atmosphere of hydrogen, helium, and methane that gradually becomes denser with depth.
When a balloon expands as it becomes warmer is it a chemical or physical change?
physical
What place is Neptune from the sun?
Its the 8th planet in the solar system however, when Pluto (which was 9th planet) until it was demoted to dwarf planet, passes inside the orbit of Neptune; Neptune then becomes the outer most planet making it the 9th. I do not know if this still counts now because of Pluto's new status.
Is Neptune's orbit unusual?
The orbits of Neptune and Pluto appear to cross each other. However, because of their alignment, they can never collide or even approach close to each other.Pluto orbits in a very long elliptical shape. Its orbit sometimes passes within that of Neptune. Then, for about 20 years, it becomes closer to the sun than Neptune.
What if the star has a bigger surface area but a smaller temperature how would that affect the luminosity?
As temperature decreases, luminosity will also decrease As radius increases (and with it surface area, but radius is a much easier to work with if you're trying to compare stars so we usually say radius) luminosity will also increase. If both are happening at the same time, it is possible that the luminosity of the star will remain more or less constant. Often one change will dominate the other, such as when a star goes through the red giant phase when the increase in radius has a far greater effect than the drop in temperature, and the star becomes more luminous.
What happens if a juvenile violates conditions of release?
He becomes your mom
What types of conditions may not be imposed by the federal government on the territory as it becomes a state?
