SC.5.E.5.2 - Recognize the major common characteristics of all planets and compare/contrast the properties of inner and outer planets. This activity is great for a class activity or an informal evaluation of the students. It sharpens the students' sorting skills, as well as comparing and contrast. Students will also demonstrate their knowledge of the difference between inner and outer planets throughout the activity, which can be use for informal assessments.
The accretion disk(circular rotating matter) solar system matter & nova remains/ binary star sucked into the hole.and jet (yet visible matter,subatomic breakdown, radiation) of a supermassive black hole. All spiral galaxies seem to have supermassive black holes at their center. That and dark matter (invisible) produce the galaxy the high speed of rotation. Jet is the still visible radiation from its breakdown of matter under it's gravity.
