1
New cards

consists of the sun, planets, their moons, and a variety of smaller objects

solar system

2
New cards

what is at the center of the solar system with other objects orbiting around it

the sun

3
New cards

what holds the objects in their orbit around it

force of gravity

4
New cards

one (__) is the average distance measured from the center of the sun to the center of earth

astronomical unit

5
New cards

how many AU does the entire solar system extend to

100,000 AU

6
New cards

a gaseous body much larger than anything else in our solar system

sun

7
New cards

how long is the sun expected to burn for

5 billion years

8
New cards

is round; orbits the sun; has cleared its orbit of other objects

planet

9
New cards

describe the 4 inner planets

closer to the sun, small, made of rock and metal

10
New cards

describe the 4 outer planets

farther from the sun, very large; made mostly of gas or liquid

11
New cards

the time it takes for one day (spin)

rotate

12
New cards

an object that orbits the sun; has enough gravity to be spherical, has not cleared its orbit

dwarf planet

13
New cards

a natural satellite that orbits a planet

moon

14
New cards

what is between a planet and its moon that keeps the moon in its orbit

force of gravity

15
New cards

small, mostly rocky bodies, found in an area between the orbits of mars and jupiter

asteroids

16
New cards

chunks of rock or dust smaller than asterioids

meteroids

17
New cards

a streak of light made when a meteoroid’s friction creates heat

meteor

18
New cards

a meteoroid that passes through te atmosphere and has hit Earth’s surface

meteorite

19
New cards

loose balls of ice and rock, have very long and narrow orbits

comets

20
New cards

what do comets develop as they orbit the sun

tails

21
New cards

describe the structure of the sun

no solid surface, completely gaseous; its mass is hydrogen and helium

22
New cards

what is hydrogen and helium in the form of in the structure of the sun

plasma

23
New cards

which state of matter is plasma

fourth state

24
New cards

very hot fluid-like gas consisting of electrically charged particles

plasma

25
New cards

what does the sun’s interior include (in order)

1- convection zone, 2- radiative zone, 3- the core

26
New cards

what is the sun’s atmosphere made out of

hydrogen and helium

27
New cards

what are the three main layers of the sun’s atmosphere

photosphere, chromosphere, and corona

28
New cards

which main layer of sun’s atmosphere is the inner layer

photosphere

29
New cards

which layer of the sun’s atmosphere is the middle layer

chromosphere

30
New cards

which layer of the sun’s atmosphere is the outer layer and looks like a white halo around the sun

corona

31
New cards

which features of the sun are the most visible

sunspots, prominences, and solar flares

32
New cards

what are sunspots

dark areas on the sun’s surface

33
New cards

sunspots are the areas of plasma (cooler/hotter) than the plasma around them

cooler

34
New cards

what does cooler plasma give off less of

less light

35
New cards

what does changing positions of sunspots indicate

the sun rotating

36
New cards

huge loops of plasma that are polarized

prominences

37
New cards

loops in sunspot regions connect, releasing large amount of magnetic energy; this energy heats plasma millions of degrees causing it to erupt into space

solar flares

38
New cards

what are eruptions called

solar flares
