Yogi Rock, analyzed by the Sojourner rover (July 4, 1997). The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust. [1] From close up, it looks more of a butterscotch, [1] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.
Color-coded elevation map, showing the elevated terrae "continents" in yellow and minor features of Venus. The Venusian surface was a subject of speculation until some of its secrets were revealed by probes in the 20th century. Venera landers in 1975 and 1982 returned images of a surface covered in sediment and relatively angular rocks. [36]
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
"Planets look more like a steady light, while stars often twinkle because their light is affected by Earth’s atmosphere," Conafoy says. Planets also might take on "distinctive colors," Conafoy says.
The majority of the frames were acquired in gray scale with the probe's Wide-Angle Camera, while the close-up views of each planet were acquired in color using the Narrow-Angle Camera. [4] The image was acquired at a distance of approximately 40.11 AU (6.0 billion km; 3.7 billion mi) from Earth and approximately 32° above the ecliptic plane. [4]
The Voyager program's discoveries during the primary phase of its mission, including new close-up color photos of the major planets, were regularly documented by print and electronic media outlets. Among the best-known of these is an image of the Earth as a Pale Blue Dot, taken in 1990 by Voyager 1, and popularized by Carl Sagan, [63]
