Earth's Position in the Universe
The Universe
Observable Universe
Milky Way Galaxy
Solar System
Inner Planets
Earth
Terrestrial
Outer Planets
Gaseous
Other Space Objects
Dwarf Planets
Kuiper Belt
Asteroid Belt
Comet
made of gas, vapor, and ice
Oort Cloud
Orbit the sun
tail points away from the sun
Meteoroids
Become meteors when they enter Earth's atmosphere because of friction
Definition of Planet
Gravity force it into a spherical shape
Orbit a star
Big enough to have enough gravity to clear its neighborhood
Orbit
Revolves (movement around the sun)
Sun has the greatest mass, therefore is the central point the planets revolve around
The Sun
Unique because it is far away from other stars
Types of Galaxies
Spiral
Eliptical
Irregular
Bound by Gravity
Stars
Hydrogen and Helium
different elements cause stars to emit different light spectra
Relationship with the Sun
Orbit/ Revalution
Roughly 265 days
Axis is 23 degrees
Orbit and axis helps create the seasons
The days with the most tilt are the solstices
The day with the least amount of tilt is the equinox
Solar Eclipse
Moon is between the Earth and the Sun
Moon casts a shadow on the earth
Sun, Moon, Earth
Rotation
Roughly 24 hours
Relationship with the Moon
Formed during the early days when gravity formed debris that collided with Earth into a spherical shape
Revolution around the Earth takes 27 days
Because the moon rotates and revolves at the same rate, we always see the same side
Moon Phases
Glows because it reflects the sun
Depend on the relative position of the sun, earth and moon
Lunar cycle is about 30 days
8 phases
Lunar Eclipse
Earth prevents the sun's light from falling on the moon
Earth casts shadow on the moon
Sun, Earth, Moon
The Moon's gravity pulls on the earth creating the tides
Gravity
The earth's gravity keeps the moon in its orbit
The moon's gravity gives Earth its tides
Stars are gas and dust held together by gravity
The sun's gravity keeps the planets in orbit because it has the largest mass in the solar system
The greater the mass, the greater the force of gravity
