Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Perihelion to Aphelion." Both terms refer to orbital mechanics. The perihelion is when the orbiting object is closest to its host star. The aphelion is when the object is furthest from its host. While we aren't able to see these changes ourselves, a filtered camera/telescope allows us to do just that. Neat stuff.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Thursday, July 8, 2021 entitled "Perihelion to Aphelion."

Wonderful blended image of the fiery globe we call the sun that provides light and heat to our planet by God's grace in creation. Whether the planet earth is at the closest point [perihelion] or at the farthest point [aphelion] in our annual elliptical orbit there is sufficient heat and light for life to blossom on earth.
Glory to God.

I pray that each of you along with those you cherish are sleeping peacefully and will awaken refreshed on Friday, July 9, 2021

APOD Background
"Explanation: Aphelion for 2021 occurred on July 5th. That's the point in Earth's elliptical orbit when it is farthest from the Sun. Of course, the distance from the Sun doesn't determine the seasons. Those are governed by the tilt of Earth's axis of rotation, so July is still summer in the north and winter in the southern hemisphere. But it does mean that on July 5 the Sun was at its smallest apparent size when viewed from planet Earth. This composite neatly compares two pictures of the Sun, both taken with the same telescope and camera. The left half was captured close to the date of the 2021 perihelion (January 2), the closest point in Earth's orbit. The right was recorded just before the aphelion in 2021. Otherwise difficult to notice, the change in the Sun's apparent diameter between perihelion and aphelion amounts to a little over 3 percent."
