Why aren't the Kuiper belt objects planet-size?Dwarf Planets:The region of the Kuiper belt has been found to contain at least 3 dwarf planets, with other discoveries possible. None of these objects, Pluto included, more than a fraction of the size of the Moon, but as they are roughly ...
Why is the Oort cloud important? Why are comets found in the Kuiper belt? Why does Rigel shine as brightly as Betelgeuse? Why do long period comets come from the Oort cloud? Why is the Oort cloud spherical? What makes Comet Encke unique?
Most obviously, it really enhances the fact that our actual moon does not have a name at all. Mars' moons Phobos and Deimos have names, all the planets have names, including exoplanets that only go by their automatically generated ones, and even the sun has a name. We don't call th...
The meeting recognized five dwarf planets – Eris, Ceres, Pluto, Haumea and Makemake. But there may be another 100 dwarf planets in the solar system and hundreds more in and just outside the Kuiper Belt. Makemake– This object orbits the Sun every310 Earth years. Haumea– This is one of ...
Is Pluto a planet or not? Who cares! Our love for the King of the Kuiper Belt is stronger than ever 95 years later Solar system guide: Discover the order of planets and other amazing facts Evidence of controversial Planet 9 uncovered in sky surveys taken 23 years apart ...
one of the largest asteroids in the Kuiper belt, observed since 1930 was only measured correctly in 2015 (a paper by Alex Dias Oliveira was published in the November issue of the Astrophysical Journal and our value, I am one of the coauthor :), gives a quite similar value to the ...
The Kuiper belt is a flat circle around the outside of the penny (like Saturn’s rings), drawn as thick as it would be if you painted it with your fingertip. The Oort cloud isn’t a disk like the other two, it’s a sphere, starting about 30 centimeters (1 ft) away from the ...
you define the neighborhood, and how you define the biggest thing in the neighborhood. arguably, pluto could be the biggest thing in its zone because it makes as much as 7 percent of the kuiper belt by mass. some researchers have tried to come up with a quantifiable way of defining that...
This month, the Earth is being visited by a comet that is nearly close enough to see with the naked eye. If you do manage to spot it, you might notice that it gives off a green hue. A green color is pretty uncommon in space, so where does the comet get this color from?
What is this big room we’re in, and who put us here? What is that bright yellow circle on the ceiling and where does it go every night? Where does the ocean end and what happens when you get there? Where are all the dead people now that they’re not here anymore?
