Observations:. Sun rises & sets every day Sun rises in East & sets in West Sun’s path in the sky is an arc Sun is at different angular altitudes in the sky at different times. The sun is never directly above (at zenith) in NY. Astronomy.

At the equator, rotation is 40,074 km/day or 1670 km/hr
31,200 km/day or 1300 km/hr
At the poles

As the Earth revolves around the sun, different constellations are visible in the night sky.
As viewed from Earth, the sun is passing through Leo (even though you can’t see the stars during the day.
The following statement sounds crazy but you'll understand it if you read it slowly!
"The axis is tilted by 23.5° from the perpendicular to the plane of its orbit."
Not drawn to scale.
The orbit is not shaped like this.

OK, Girls & Boys, time for an activity on seasons and the tilt of the Earth!

Notice the changing diameter of the Moon during the 'moonth'. As the Moon's orbit brings it closer to earth (perigee) at the New Moon, it appears larger to us. Also notice how the Moon 'rocks' up and down and back and forth. That happens because the Moon's orbit takes it above the Earth's equator (allowing us to see more of the south polar region) and below the equator revealing more of the north polar region of the Moon. The back and forth (east-west) rocking is due to the changing orbital velocity of the moon.
Here are the traditional names given to each month's full moon from the "Old Farmer's Almanac":
January Wolf Moon
February Snow Moon
March Worm Moon
April Pink Moon
May Flower Moon
June Strawberry Moon
July Buck Moon
August Sturgeon Moon
September Harvest Moon
October Hunter's Moon
November Beaver Moon
December Cold Moon
m1 and m2 are masses of the objects
d is the distance

1.008 x 4 = 4.032
4.032 – 4.0026 = .0294
E = energy
m = mass
c2 = speed of light squared
.0294 x 186,000 x 186,000 = a lot from a little
