A Mesmerizing Animation Shows Just How Weird Our Solar System Is

NASA ’s Kepler space telescopespotted M of worldsduring its four - year mission , prove that our galaxy is filled with planets . But even more surprising is what the Kepler database highlights about our own solar system : namely , that we ’re a bunch of celestial oddballs .

That fact is made obvious by Kepler Orrery IV , an invigoration produced by astronomy graduate scholarly person Ethan Kruse of the University of Washington . In it , Kruse compares the range of hundred of exoplanets in the Kepler database to that of our own solar system , show on the right . The brio suggest the comparative size of it of the Kepler planet ( although obviously not to scale compared with their stars ) , as well as their open temperatures .

Once you get over the spellbinding effect of all those twirling dots , you ’ll start to notice just how strange our planetary choreography is . Before the Kepler delegacy began in 2009 , astronomers assumed that most exoplanet system would be constructed like our own : small rough reality toward the center , large gas giants hovering around the periphery . But when scientist started notice planetary transit events en masse , we clear we were n’t being intimately imaginative enough .

Kepler revealed “ hot Jupiters , ” elephantine - sized throttle planet practically touching their parent stars , and rocky lava universe orbit much close than Mercury . As Kruse explains , the nature of Kepler ’s detection method acting is predetermine toward satellite in tight orbits . “ Smaller arrangement orbital cavity quicker , so over the four years of Kepler ’s life we honour many more transits which makes them light to find , ” he told Gizmodo . “ Also , littler system have a higher probability to be aligned just the right style for the major planet to pass in front of the champion create the passage signal Kepler needs to notice a planet . ”

“ That say , it is interesting just how uncouth these very compact systems are , ” he continued . “ [ It ] has made a number of astronomers enquire why our Solar System does n’t have any very short period planets . ”

One theory posit that our Solar System once harbour a primeval clan of planets on close , but fluid cranial orbit . Perhaps these luckless earth fall into the Sun or were flung violently out of the Solar System long ago . “ It ’s still too former to tell , but these very compact Kepler systems are definitely helping us refine our theories about major planet formation , ” Kruse say .

Kepler Orrery IV — the “ subsequence ” to theKepler Orrery seriesproduced over the year by the University of Santa Cruz ’s Dan Fabrycky — prove all of the Kepler multi - planet systems to date ( 1705 planets in 685 system ) . Kepler ’s primary mission ended in 2013 after the quad telescope lost two of its stabilizing reaction wheels , but the treasure trove of data it pull together has continued to give discoveries ever since .

“ [ Fabricky ] has been busy and had n’t relinquish [ a Kepler Orrery ] in two years even though we ’ve in all probability at least doubled the amount of known planets and system since then , ” Kruse say . “ Now that the Kepler missionary work is over , this will in all likelihood be pretty close to the final version . ”

Kruse , for his part , hopes to continue sharing science and data with the public through clever invigoration , so we ’re frantic to see what he cooks up next .
