{{Main|Planetae}}
Mercury and Venus are visible only in twilight hours because their orbits are interior to that of Earth. Venus is the third-brightest object in the sky and the most prominent planet. Mercury is more difficult to see due to its proximity to the Sun. Lengthy [[twilight]] and an extremely low angle at maximum [[Elongation (astronomy)|elongation]]s make optical filters necessary to see Mercury from extreme polar locations.<ref>{{Cite web |url=http://www2.wwnorton.com/college/astronomy/astro21/sandt/latitude.html |title=Sky Publishing – Latitude Is Everything<!-- Bot generated title --> |access-date=2007-07-14 |archive-date=2017-03-24 |archive-url=https://web.archive.org/web/20170324061045/http://www.wwnorton.com/college/astronomy/astro21/sandt/latitude.html |url-status=dead }}</ref> Mars is at its brightest when it is in [[Astronomical opposition|opposition]], which occurs approximately every twenty-five months. Jupiter and Saturn are the largest of the five planets, but are farther from the Sun, and therefore receive less sunlight. Nonetheless, Jupiter is often the next brightest object in the sky after Venus. Saturn's luminosity is often enhanced by its rings, which reflect light to varying degrees, depending on their inclination to the [[ecliptic]]; however, the rings themselves are not visible to the [[naked eye]] from the Earth.{{citation needed|date=October 2023}}
