Mar 8, 2024 · Tell students that the Earth moves around the sun in an elliptical orbit and is tilted on its axis. Explain that as Earth orbits the sun, it rotates on its axis, and the axis is always pointed in the same direction. Have the students representing the Earth and sun in each group stand approximately 5-7 feet apart. Dim or turn off the lights. 4.

- Earth's Lopsided Orbit
Many people believe that Earth is closer to the Sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the Sun in the winter. Although this idea makes sense, it is incorrect. It is true that Earth's orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the Sun tha...
Long, long ago, when Earth was young, it is thought that something big hit Earth and knocked it off-kilter. So instead of rotating with its axis straight up and down, it leans over a bit. By the way, that big thing that hit Earth is called Theia. It also blasted a big hole in the surface. That big hit sent a huge amount of dust and rubble into orbi...
Earth's perihelion (point closest to Sun) = 91,400,000 miles from Sun Earth's aphelion (point farthest from Sun) = 94,500,000 miles from Sun While that is a difference of over 3 million miles, relative to the entire distance, it isn’t much. And, believe it or not, aphelion (when Earth is farthest from the Sun) occurs in July, and perihelion (when w...
The two main forces and effects of Sun on Earth are: (1) the electromagnetic radiation that supports life on Earth; and (2) the gravitational force that keeps the Earth in orbit. This gravitational pull also holds in place the Earth’s atmosphere (Carnegie Mellon University, 2003). Source: Carnegie Mellon University (2003) Figure 1.

Feb 16, 2024 · The degree of Earth’s tilt is not random; it’s a precise 23.5 degrees from the vertical. This tilt remains relatively stable over long periods, thanks to the gravitational influences of the moon and the sun, which help to stabilize Earth’s orientation in space. This consistency maintains the regular cycle of seasons as we know them.
Earth to complete one orbit exactly, with respect to the stars. •1 sidereal year = 365d 6h 9m 10s ≈ 365.25 days •A tropical year is the time it takes for the Sun to go from vernal equinox and back (ecliptic crosses the equator) •1 tropical year = 365d 5h 48m 46s ≈ 365.24 days •We use the tropical year
