the first step in the formation of a star, a cloud of gas and dust; usually made up of 70% hydrogen, 28% helium and 2% other elements
Nebula
Star's mass, size, and density do not vary with all stars. They are all the same
Flase
small bodies made of rock and metal; have a diameter of about 1m
Meteoroids
a special tool that concentrates electromagnetic radiation that it groups from the sky so we can see it better
Telescope
pieces of rock that revolve around the sun in an ellipse, usually bigger than comets and meteorites
Asteroid
a cloud of gas that surrounds a dying sun-like star
Planeary Nebula
apparent magnitude is how bright a star looks when you see it from earth
True
streak of light that is created when a meteoroid burns as it travels through the earth's atmosphere
Meteor
Who and when was the first telescope used?
Lippershay, early 1600s
How are Asteroids classified?
they are classified from what they're made of
a star that gets brighter suddenly is called...
Nova
Red Giants are not very bright and are extremely hot
False
the portion of a meteoroid that is remaining once it goes through the earth's atmosphere and hits earth; 1kg or less
Meteorite
Optical Telescopes
What Comet is seen every 76 years and is set to seen next in 2061?
Halley's comet
a small and dense ball of neutrons that spins very quickly
Neutron Star
When helium becomes carbon/oxygen no more fusion will happen
True
What is known as a shooting star?
a) Meteor
b) Meteoroid
c) Meteorite
What are the two types of telescopes?
refracting/reflecting
a celestial body that are usually small and composed of ice, rock and dust, they have elliptical orbits around the sun and usually have a diameter of 1-100km
Comet
when a star has a big explosion and whole star blows up, this is isn't common for white dwarfs and very common for red supergiants
Supernova
White dwarfs are not very hot but extremely bright
False
The three types of Meteorites are:
stony, iron, stony-iron
What is the biggest telescope there is?
The James Webb telescope
cloud of dust and ice outside of Neptune's orbit that people think is where the majority of comets come from
Oort Cloud
