NakedEyePlanets.com is built around a wonderfully old-fashioned astronomical question: what can you identify with your actual eyes if somebody explains where to look?
Martin J. Powell’s site is a large independent guide to Mercury, Venus, Mars, Jupiter, Saturn and the fainter outer planets, mixing observational advice with star maps, ephemerides, photography, historical notes and current visibility tables.
The homepage is still actively useful in 2026. It includes a month-by-month planet-visibility table and links to planetary positions through 2030. That makes the site unusual in the Ancient Web collection: the structure feels like an older personal reference page, but the astronomical data keeps moving forward.
The basic observing advice is excellent because it explains what the eye is actually seeing.
Planets shift against the background stars from night to night. Bright stars often twinkle more visibly because they are effectively point sources distorted by atmospheric turbulence, while the apparent disks of planets tend to produce steadier light. The page discusses apparent magnitude, angular size, albedo, conjunctions, elongations and apparitions without turning the explanation into a textbook wall.
The sky is a calendar if you know the vocabulary
One of the site’s strengths is that it gives readers the words needed to keep learning.
An “apparition” is the period when a planet is observable during a particular cycle. Mercury and Venus alternate between morning and evening appearances. Superior planets move through longer cycles and are often easiest to observe around opposition. Star charts place them near the ecliptic through the zodiac constellations.
The site also preserves observing history. It explains the classical names of the planets, the Greek and Roman associations behind them, Pluto’s 2006 reclassification and early telescopic discoveries such as Galileo’s observation of the phases of Venus.
Powell uses his own photographs to show how planets actually appear in the sky rather than only presenting spacecraft images. That matters. A Hubble photograph of Jupiter is beautiful, but it does not teach a beginner how to recognize the bright white point above the horizon from a parking lot.
The page is dense in the best old-Web sense: one long document branches into tables, finder charts, definitions, biographies and older apparition maps rather than forcing the visitor through a slideshow interface.
For CacheRat’s Ancient Web research list, this is a good reminder that independent reference sites did not have to become obsolete when they aged. Some simply kept updating the numbers.
The planets wander.
The URL, admirably, does not.
