Pluto's color changes as it makes its closest approach?

In summary, the conversation is about the seasonal color changes on Pluto, specifically the black spot next to the bright spot and whether the addition of extra atmosphere during its closest approach to the sun has affected these colors. The frequency of photos taken by Hubble of Pluto is also discussed, with the understanding that Hubble's main purpose is for scientific research and there is high demand for its imaging time.

Pluto's changes as it makes its closest approach?
I've seen the photos from Hubble showing the seasonal color changes on Pluto.

Just wondering if the addition of the extra atmosphere as it makes its closest approach to sun, has changed the any of the colors on Pluto, in particular the black spot next to the bright spot?

How often do we get photos of Pluto from Hubble? Daily? Weekly? Monthly? Help I'm ignorant in that area!

Hmmm. Not sure.

Hubble is designed for, and mainly does, scientific research images. Most are not "pretty pictures". Scientists around the world submit proposals to get time on the HST for their research, and the telescope is always in very high demand. Most proposals are denied as there are far more demand for imaging time than is available.
 

FAQ: Pluto's color changes as it makes its closest approach?

What causes Pluto's color changes?

The color changes on Pluto are caused by the different levels of sunlight it receives as it orbits the sun. As Pluto makes its closest approach, it receives more sunlight which causes its surface to warm up and change color.

Why does Pluto's color change during its closest approach?

Pluto's color changes during its closest approach because of its highly elliptical orbit. As it gets closer to the sun, it receives more sunlight and its surface temperature increases, causing it to appear brighter and more red in color.

How does Pluto's distance from the sun affect its color?

Pluto's distance from the sun directly impacts its color. As it moves further away from the sun, its surface temperature decreases and it appears darker and more reddish in color. Conversely, as it gets closer to the sun, it appears brighter and more yellowish in color.

Do other factors besides sunlight play a role in Pluto's color changes?

Yes, other factors such as the composition of Pluto's surface also play a role in its color changes. Different types of ices and other materials on the surface can reflect light differently, resulting in changes in color.

Will Pluto's color continue to change as it makes future closest approaches?

Yes, Pluto's color is expected to continue changing as it makes future closest approaches to the sun. This is due to its highly eccentric orbit and the varying levels of sunlight it receives during different points in its orbit.
