Planets Visible With the Naked Eye By Jennica Bringhurst Introduction I will be discussing three main points about the planets in the night sky. How to identify the planets from the stars The appearance of the planets in the night sky The visibility of the planets in 2012 Identifying the Planets from the Stars Planets and Stars Apparition and Opposition The Planets positions changes Planets brightness varies and they shine with a more steady light then the stars . Plants do not produce any light of their own. Stars are so distant they appear to twinkle Stars generate their own light. Apparition -The period of time during which any given planet can be seen Opposition- is when one celestial body is on the opposite side of the sky when viewed from a particular place Mercury Apparent Magnitude: -1.9 to +3.8 More difficult to spot than the other bright planets Best seen in March and April evenings and September and October mornings. White in color and can take on a somewhat pinkish hue Twinkles more readily Venus Apparent Magnitude: -4.7 to -3.5 Easiest planet to see with the naked eye Cycle of alternating morning and evening appearances Mars Apparent Magnitude: -2.9 to +1.8 Popularly called the red planet Distance from Earth varies considerably Mars can clearly be seen in twilight for about six weeks Star map showing the path of Mars through Gemini, Cancer, Leo and Virgo from September 2011 to August 2012 Jupiter Apparent Magnitude: -2.9 to -1.6 Appears bright white Can be seen in twilight Largest of the solar system planets, but is not the brightest when seen from earth . Star map showing the path of Jupiter through Pisces, Aries, Taurus and Gemini from May 2011 to July 2014 Saturn Apparent Magnitude: At opposition -0.5 (rings open) to +0.9 (rings edge-on) Appears pale yellow The rings contribute to its brightness. You can see Saturn moon Titan with binoculars. Star map showing the path of Saturn thro ugh Leo and Virgo from September 2006 to December 2013 Uranus Apparent Magnitude: +5.5 (average at opposition) Star map showing the positions of Uranus from Aquarius through Pisces between 2006 and 2019 Uranus is barley visible to the naked eye when at its brightest, but there has to be no light pollution to see this planet. It is the most distant planet visible to the naked eye. Visibility of the Planets in 2012 • • • Dawn- the planet is visible in the eastern sky for an hour or so before sunrise Dusk- the planet is visible in the western sky for an hour or so after sunset. Mor- the planet is best seen in the morning sky. • Eve- the planet is best seen in the evening sky. • AN- the planet is visible all night. • - The planet is too close to the sun and is not visible Conclusion Position of the planets in the Constellations I hope this information has given you a better understanding of the night sky. Perhaps the next time you are outside with a group of people you can look up at the night sky and impress whoever you are with teaching them about the naked eye planets.
