There exists a dwarf planet, Haumea, past the orbit of Neptune that is the fastest spinning planet or dwarf planet in the Solar System by far. How fast? Well Haumea is a third the mass of Pluto, but rotates once every 3.5 hours. This is so fast it puts a lot of stress on the dwarf planet and makes it look like an ellipsoid– as in, normally it would be fairly spherical like a tennis ball, but is spinning so fast that Haumea is twice as long as it is wide (so like a lentil).

There is a star in our galaxy that is 5 billion times volume of our sun.
Some astronauts experience a profound shift in life perspective after seeing Earth from space.
