Some people think that this is why we have seasons, but they are wrong. Earth reaches perihelion, ... The difference in distance is not the cause of our seasons. Instead, seasons are caused by the tilt of Earth's axis. ... If an object orbits something other than the Sun, we don't use the terms perihelion and aphelion.

The specific proximal (close) and distal (far) points along Earth's orbit around the sun are called "perihelion" and "aphelion," respectively, ... The seasons are caused more by the tilt of the earth's axis with respect to the sun. In summer, the northern hemisphere is tilted toward the sun. It gets more direct solar...

The fact that we, in the northern hemisphere, are colder/warmer when near perihelion/aphelion is primarily due to the seasons, which are caused by the tilt ...

Earth was last at perihelion on January 3, ... Right now, it is summer in the northern hemisphere, even though we are at our farthest point from the Sun. It is winter for us in the northern hemisphere when we are closest to the Sun. The seasons are caused by the tilt (inclination) of the Earth, not it’s distance from the...

The four seasons are spring, summer, autumn (also called fall), and winter. Some elementary textbooks claim that seasons are caused by the Earth getting slightly closer to the Sun at perihelion, resulting in higher temperatures.

We have all been taught that the seasons are caused by the tilt of the Earth's axis of rotation - the 23.4° offset of the axis from a direction perpendicular to the Earth's orbital plane. The direction of the rotational axis stays nearly fixed in space, even as the Earth ... Equinoxes, Solstices, Perihelion, Aphelion...

USATODAY.com Latest News ... Earth's tilt creates seasons ... "Averaged over the globe, sunlight falling on Earth in July (aphelion) is indeed about 7% less intense than it is in January (perihelion)," says Roy Spencer of the Global Hydrology and Climate Center in Huntsville, Alabama.

Bad Astronomy: The seasons are caused by the change in the distance of the Earth to the Sun. ... The Earth reaches perihelion (the point in its orbit closest to the Sun) in January, and it reaches aphelion (farthest point from the Sun) some six months later. If that were all that governed weather, we'd have summer in...

The shift, on the orbit, of the moments of the seasons, thus, for example, is shifting the relationship between summers and winters, and the aphelion and the perihelion...

perihelion and aphelion, 5 million miles, martian climate: Kai, Yes, Mars 25 degree axial tilt gives Mars 4 seasons, just like the Earth, during its 687 day (1.88 year) orbit around the sun. BUT, an additional factor gives Mars more extreme summers and winters because you have to factor in its variable distance...
