Dear MEL
Topic Readers,
Newly
discovered dwarf planet takes 700 years to orbit the sun
What is a
dwarf planet? It’s any planetary-mass object that is neither a planet nor a
natural satellite. It orbits the Sun directly and not be a moon around another
body. It is also massive enough for it to have become spherical in shape under
its own gravity.
So why finding
such an object in outer space is so important? Unlike the moon or Mars, it sounds
too far and little to do anything to do with human’s life or business.
In fact,
it is pretty meaningful for astronomers to study because they could tell them
how they were formed, which eventually could give more clues how the solar
system was created.
What the
life is like to take 700 years to go around the sun? How many seasons, if any,
are there on the little icy and lonely object?
Enjoy reading
and learning about planets and dwarfs of the solar system.
