What are Overshadow Planets?
Dwarf planets are little planets that circle the Sun similar to the other planets within the Sun powered Framework.
But they are not called full planets since they dont meet all the rules set by scientists.
Imagine a little planet that tries to be like Soil or Jupiter but doesnt very fit in.
Thats a overshadow planet!
Definition of a Overshadow Planet
In 2006, researchers from the Worldwide Galactic Union (IAU) gave a clear definition of what a overshadow planet is. Concurring to them, a overshadow planet must:
1. Orbit the Sun.
2. Be nearly circular in shape.
3. Not be a moon of another planet.
4. Not clear its way (circle) of other space rocks and objects.
Note: Clear its path implies that a genuine planet like Soil or Defaces has pulled in or pushed absent littler rocks and objects from its path. Dwarf planets share their circles with other space objects.
The Most Distinction: Planet vs. Overshadow Planet
Lets get it this with a basic table:
Feature Planet Dwarf Planet
Orbits the Sun Yes
Round Shape Yes
Not a Moon Yes
Cleared Orbit Yes
Example:
Earth could be a planet since it clears its orbit.
Pluto could be a overshadow planet since it does not clear its orbit.
Popular Overshadow Planets in Our Solar System
There are five authoritatively recognized predominate planets by the IAU, and there may be hundreds more within the future!
Pluto
Once the 9th planet of our Sun powered System.
Found within the Kuiper Belt (a region of frosty objects past Neptune).
Has 5 moons, the biggest is Charon.
Pluto is littler than Earths Moon.
Fun Reality: Pluto is made of ice and shake and has mountains made of ice!
Eris
Located more distant than Pluto within the Kuiper Belt.
Slightly littler than Pluto, but heavier.
Has one moon named Dysnomia.
Caused the wrangle about that driven to Pluto getting to be a overshadow planet!
Fun Reality: Eris takes approximately 557 a long time to go around the Sun once!
Haumea
Also within the Kuiper Belt.
Shaped like a football due to its quick rotation.
Has two moons.
Surface is made of frigid crystals.
Fun Fact: Haumea turns so quick, it completes one turn in fair 4 hours!
Makemake
Slightly smaller than Pluto.
Very shinning and icy.
Discovered in 2005.
Has one little moon.
Fun Reality: Makemake was found around Easter, and is named after a god of creation from Easter Island mythology.
Ceres
Found within the space rock belt between Damages and Jupiter.
Is the as it were predominate planet found within the inward sun powered system.
Discovered in 1801.
Has no moons.
Fun Reality: Researchers accept Ceres has water ice beneath its surface and may have once had an ocean!
Where Do Overshadow Planets Live?
Dwarf planets are found in two fundamental places:
A. The Space rock Belt
Between Defaces and Jupiter.
Only Ceres is found here.
B. The Kuiper Belt
A gigantic frosty ring past Neptune.
Home to Pluto, Eris, Makemake, and Haumea.
Filled with frigid rocks, comets, and predominate planets.
Case: On the off chance that our Sun oriented Framework is like a house, at that point the Kuiper Belt is just like the terrace full of frigid toys!
Why Was Pluto Changed from a Planet to a Predominate Planet?
Pluto was found in 1930 and was called the 9thplanet. But researchers afterward found that Pluto:
Was as well small.
Had an bizarre orbit.
Did not clear its circle of other objects.
So, in 2006, Pluto was renamed as a predominate planet.
Which means Pluto isn’t a full planet any longer, but its still vital and special!
How Do Researchers Find Overshadow Planets?
Scientists utilize effective telescopes to see profound into space. They:
1. Watch for little, moving objects within the sky.
2. Use computer program to consider their path.
3. Measure the objects estimate, shape, and orbit.
In some cases, shuttle like Modern Skylines visit these faraway predominate planets to send back pictures and information!
Significance of Examining Predominate Planets
Why ought to we care around these little planets?
They offer assistance us get it how the Sun based Framework was formed.
They may have water or ice, which is imperative for life.
They appear us that the Sun oriented Framework is greater than we thought!
Case: Considering Ceres might offer assistance us learn approximately water on other planets!
Names and Meanings
Most predominate planets are named after legendary divine beings and goddesses:
Dwarf Planet Name Origin
Pluto Roman god of the underworld
Eris Greek goddess of strife (fitting since it caused debate!)
Haumea Hawaiian goddess of childbirth
Makemake God of creation in Easter Island mythology
Ceres Roman goddess of cultivating and crops
Predominate Planets vs. Moons vs. Asteroids
Feature Dwarf Planet Moon Asteroid
Orbits Sun? Yes No (circles a planet) Yes
Round shape? Yes Sometimes Usually not
Size Small Small/Medium Tiny
Location Kuiper Belt / Space rock Belt Near planets Mostly in Space rock Belt
Fun Facts for Kids
1. A few overshadow planets are so distant that it takes hundreds of a long time to circle the Sun!
2.They are made for the most part of ice and rock.
3. Plutos moon Charon is nearly as huge as Pluto!
4. Predominate planets within the Kuiper Belt are solidifying cold.
5. We keep finding unused overshadow planet candidates each few a long time!
