Planets in Our Solar System
A planet less dense than water
Saturn
The north star is also called this
Polaris
Which color on the visible spectrum has the most energy?
Blue
How are a red giants solar flares different from our suns?
They happen much more often/more frequently
a celestial object made of ice, gas and some rock
comet
The name of our galaxy
the milky way
How tall are radio waves?
as tall as buildings
What determines if a massive star becomes a black hole or a neutron star?
Mass, a star over 20x greater (much larger) in mass than our sun will collapse from their own gravity becoming a black hole.
A star that lines up (almost) perfectly with earth's axial tilt
Polaris (north star)
The distance from the ground up to the star
altitude
How are energy and wave length related?
What comes before a typical or a massive star? Be specific, more than just the name.
Nebula; cloud of space dust which begins to swirl, gravity slowly pulling mass towards the center.
why stars appear brighter than others
size and distance from the earth
Which side of the Electromagnetic Spectrum is more dangerous (larger or smaller waves). Why?
Smaller waves, they have more energy (eventually enough energy to knock electrons off atoms).
What is the final "stage" of a typical star? What should you know about it?
White dwarf, remaining core that is still giving off light but no longer producing new energy. Will slowly cool off over millions of years.
The four outer planets all have this in common. Please name them as well.
All gaseous planets.
Saturn Jupiter Uranus Neptune
A rock pebble that has entered our atmosphere, but not landed
Meteor
The sun is made of mainly these two elements.
Hydrogen and helium
How do we find which elements are in stars, using the "barcodes" from spectroscopy?
Light from a star's atmosphere absorbs specific wavelengths (colors) of light, we can study the remaining "barcode" and compare it to individual elements "barcodes" to determine the star's makeup
List all of the things you should know about a red giant.
-H runs out in the core
-Core compresses, temperatures rise
-He can now fuse into carbon
-Greater outward energy means star gets larger
-More solar flars
