The Solar System
Our Solar Neighborhood and Why It Matters
We live in the Milky Way—a galaxy named for its milky, luminous appearance. At its heart burns a star we call the Sun, orbited by planets, moons, asteroids, and even space debris. For this discussion, let’s focus on the nine planets that once defined our cosmic neighborhood.
When I was in elementary school, we were taught there were nine planets. But in 2006, Pluto was reclassified and dropped from the official list due to taxonomy changes. Still, Pluto continues to orbit the Sun, classification aside. Starting from Pluto and moving inward, we find eight planets, each with its own striking singularity. But for practical purposes, here’s what matters: Earth is the third planet from the Sun, and just beyond us lies Mars. Let’s remember that—Mars is next. And relatively soon, humans will reach it. That astronaut? Likely already born.
How Hot Is the Sun?
Temperatures at the Sun’s core reach into the millions. For your records, keep in mind: surface temperatures hover around 27 million degrees Fahrenheit (15 million Celsius). Though the Sun’s true color is white, our atmosphere filters it into the familiar golden hue—and offers only modest UV protection.
Does this matter? Absolutely. Especially when boating—whether sailing or motorboating—sun protection is paramount. Not just for your vessel and gear, but for your crew and passengers. That radiant blessing we receive from the Sun must be managed with care.
Here’s my pitch: invest in a quality Bimini top and dodger, a full enclosure or retractable shades for your boat. And don’t forget covers for your cherished toys—dinghies, jet skis, skiffs, runabouts, and powerboats. My sincere advice: protect yourself and your valuables from the sun and the elements. That’s my two cents.
Wrapping Up
In this issue, we’ve covered the basics of the solar system—its simple definition and composition. More importantly, we’ve touched on the vital need to manage UV exposure and weather effects on people and possessions.
In our next issue, we’ll explore planetary orientation, their motion within the system, and the implications of these configurations. As a preview: the position and trajectories of planets around the Sun define what we call “weather” here on Earth. And weather, as we know, is everything.
Be safe out there,
