THE UNIVERSE lets take a second look

relative distance

relative distance in the context of our discussion of the Universe is the perceived size of an object in relationship to our distance from the object

closer objects

objects that are closer appear larger, more focused, and brighter

farther objects

objects that are farther away appear smaller, less focused, and duller

So, what does it mean?

larger objects in our Universe that are farther away appear smaller than smaller objects that are closer because of our relative distance

and given that smaller objects in our Universe that are closer appear larger than larger objects that are farther away because of our relative distance

celestial objects

celestial objects are natural objects which are located outside of Earth's atmosphere, such as the Sun, a planet, a moon, a comet, an asteroid, a meteoroid, or a star


move or cause to move in a circle around an axis or center

celestial objects rotate on an axis


move in a circular orbit around

celestial objects revolve around other celestial objects

the Earth revolves around our Sun

Our Moon revolves around the Earth

24 hours or a day

it takes the Earth approximately 24 hours to rotate on its axis

this rotation creates night as we rotate away from the Sun and day as we rotate back towards the sun

29 1/2 days or a month

the Moon's revolution around the Earth takes approximately 30 days, or a month, this is called the Lunar Cycle

the Lunar Cycle marks a month on Earth

365 1/4 days or a year

it takes the Earth 365 1/4 days to revolve around the Sun

the revolution of the Earth around the Sun marks a year
