Been wishing on a star lately and your wishes haven’t come true? Maybe you’ve been wishing on a planet — Jupiter. At its brightest in six decades. And it’s up all night. Hard to miss. Just keep looking up. — PolitiTweet.org

While everybody is arguing & fighting over all manner of terrestrial issues, @NASA’s Double Asteroid Redirect Mission (DART) slams a space probe into an asteroid’s moonlet today. Consider it practice, deflecting killer asteroids that might head our way. https://t.co/kfuyZZI76v — PolitiTweet.org

Both Earth & Jupiter (as do all planets) have oval orbits around the Sun. Every now and then, Earth is farthest from the Sun while passing Jupiter when it’s closest to the Sun. That’s what’s going on next week, accounting for Jupiter’s extra brightness in the night sky. — PolitiTweet.org

Sept 23, 2022 This coming week, Earth passes closer to Jupiter than in six decades. Rising at sunset & setting at sunrise, look for it overnight — the brightest "star" in the sky. Jupiter, at its closest, exerts a force of gravity on Earth 5x higher than when at its farthest — PolitiTweet.org

9:04pm ET -- September 22, 2022 Happy Equinox to all residents of Planet Earth. In the N. Hemisphere, summer ends -- the longest of the four seasons: checking in at 93 days, 15 hours. Over that time, Earth orbits farther from the Sun, traveling more slowly than average. — PolitiTweet.org

The time has come for those of us who write non-fiction to rise up and adopt the word “faction” so that we’re no longer forced to live in the negation of another genre. — PolitiTweet.org

Mathematically, most people are not “Suckers.” Worldwide, about four people are born every second. If a sucker is born every minute (as legend declares) then only one in 240 people is a sucker. Just sayin’. — PolitiTweet.org

Is it just me, or has autocorrect gotten more aggressive lately? The rampant insertion of properly spelled WRONG words. I’d rather you criticized my clumsy typing of words you still recognize than think I can’t contours a sentence. — PolitiTweet.org

If interested, Barnes & Noble has just offered for sale a limited edition of autographed pre-order copies of Starry Messenger. Yes, I personally signed each one. With a fancy-pants fountain pen, in purple ink — my favorite color. https://t.co/DNkovzZNc1 — PolitiTweet.org

Geeky thing to do tonight: Locate the Harvest Moon on the sky relative to any pattern of nearby stars. Go inside for 1-hour and do chores you should've done earlier. Come back out: the Moon moved east by its own diameter relative to those stars. That’s the Moon orbiting Earth. — PolitiTweet.org

When you admire the Full Moon late this evening, look nearby on the sky and notice a very bright star. If you wished on it, and your wishes did not come true, it’s because that “star” is planet Jupiter. After the Sun & Moon, the brightest object in the sky this month. — PolitiTweet.org

Earth turning within the oceanic tidal bugle caused by the Moon causes water to slosh on our coastlines. We experience this as the “tide coming in" and the "tide going out.” This, along with other factors such as earthquakes and melting glaciers, changes Earth’s rotation rate. — PolitiTweet.org

Harvest Moon continues this evening, rising at sunset and setting at sunrise. Not that you asked, but the Moon is spiraling away from Earth at about 1.5in (4cm) per year. In response, Earth’s rotation is slowing down, requiring occasional leap seconds -- twenty-seven since 1972. — PolitiTweet.org

While you admire the Harvest Moon this evening, don’t search for the non-existent “Man in the moon.” Instead, identify Wilma Flintstone, in profile, clearly visible in the lunar terrain. https://t.co/8FDhW1du3g — PolitiTweet.org

As you admire the rising Full Moon over the eastern horizon, if you think it's huge, you're a victim of the “Moon-on-Horizon illusion," where the Moon among hills or trees or buildings looks much larger than it actually is. One reason for science — to bypass sensory delusions. https://t.co/vzqYWosy6v — PolitiTweet.org

Just to be clear, Full Moons impart no more (or less) gravity or tidal forces on Earth than any other phase. The very high (and very low) tides we see during Full Moons come from the Sun’s tidal forces adding directly to the Moon’s. — PolitiTweet.org

Full Moon tonight — the closest one to the September 22 equinox. Northern Hemisphere cultures traditionally calls this one the “Harvest Moon.” Full Moons rise at sunset & set at sunrise — the only phase to do so — allowing farmers to pick crops throughout the night. https://t.co/5SOSnGceds — PolitiTweet.org
