Why Pluto is no longer a planet?

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

How cold is Pluto at night?

At its coolest, temperatures can fall to minus 387 degrees F (minus 233 C).

What planet is bigger than Pluto?

Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km). Discovered in 2003, Eris orbits at an average distance of 68 AU (that is, 68 times the Earth’s distance from the sun) and takes 561.4 Earth years to circle the sun.

Is Pluto or Mercury bigger?

In fact, Mercury is closer in size to our Moon than to Earth. In case you’re wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto’s equatorial diameter is just 2,302 km, about half Mercury’s width.

Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.

How cold is Titan?

The surface of Titan is one of the most Earthlike places in the solar system, albeit at vastly colder temperatures and with different chemistry. Here it is so cold (-290 degrees Fahrenheit or -179 degrees Celsius) that water ice plays the role of rock.
