Terms Flashcards
Absolute magnitude
How bright the star appears to be
Apparent magnitude
The amount of light a star would give off if they were at the same distance from earth
Apparent magnitude
The amount of a star would give off if they were at the same distance from earth
Apparent magnitude
The amount of a star would give off if they were at the same distance from earth
Asteroid
Small celestial objects, composed of rock and metal
Asteroid belt
Ring of many asteroids
Astronomical unit
150 million km
Astronomy
The study of things beyond earth
Aurora
Solar winds from the corona hit the earths atmosphere and spiral along the earths magnetic field. The strike gases in the earth atmosphere creating a light display called auroras
Blue shift
Low wavelength but high frequency
Celestial object
Any object in space
Chromospheres
The inner atmosphere very hot
Comet
Chunk of ice, dust and rock that travels in a very long orbit around the sun
Constellation
Gripping stars a scene from earth
Convective zone
Cool matter, sinks in hot matter, rises in this area
Corona
Hot outer regions of the sun extends millions of kilometres into space
Dwarf planet
Smaller planet that does not satisfy the three regulation to be a planet
Luminous
Emit huge amounts of energy and light
Meteor
Shooting star meteorite that has been pulled into atmosphere by gravity were fiction cause them to burn up
Meteorite
Rock that comes from Astrid or debris left behind by comments and hits earth before vaporizing
Meteoroid
Piece of metal or rock that is smaller than an
Asteroid
Neap tide
Very weak tides, sun and moon are perpendicular to one another with respect to earth and pull of sun contearacts pull of moon
Non-luminous
Reflectly from the sun
Nuclear fusion
Particles collide, and fused together, for example, hydrogen and hydrogen collide and fuse to helium in the sun and other celestial objects
Polaris
North Star
Precession
The changing of the direction of the earths axis
Radioactive zone
The energy from the core comes out in this layer
Red shift
High frequency low wavelength
Spring tide
Rising and falling of the surface of a large body of water due to interactions between the moon earth and sun the gravitational pull of the moon pulls the Earth closer to it’s causing a bulge of water forming on opposite sides of the Earth(every six hours). If the sun earth and moon are aligned creates very high tide.(spring tides).
Star
Giant ball of hot gases that produce in energy(light)
Star map
Show the position of stars in the sky
Sunspot
Dark region of cool matter in the sun’s surface caused by changes in the suns magnetic field
