APOD: Mars and Meteor over Jade Dragon... (2020 Nov 21)

Post by APOD Robot » Sat Nov 21, 2020 5:06 am

Image Mars and Meteor over Jade Dragon Snow Mountain

Explanation: A brilliant yellowish celestial beacon, Mars still dazzles in the night. Peering between clouds the wandering planet was briefly joined by the flash of a meteor in this moonless dark sky on November 18. The single exposure was taken as the Earth swept up dust from periodic comet Tempel-Tuttle during the annual Leonid Meteor Shower. The view of a rugged western horizon looks along the Yulong mountain range in Yunnan province, southwestern China. Yulong (Jade Dragon) Snow Mountain lies below the clouds and beyond the end of the meteor streak.

https://en.wikipedia.org/wiki/Jade_Dragon_Snow_Mountain wrote:
<<Jade Dragon Snow Mountain (Chinese: 玉龍雪山) is a mountain massif or small mountain range in Yulong Naxi Autonomous County, Lijiang, in Yunnan province, China. Its highest peak is named Shanzidou (扇子陡) and is 5,596 m above sea level.

The Jade Dragon Snow Mountain massif forms the bulk of the larger Yulong Mountains, that stretch further north. The northwestern flank of the massif forms one side of the Tiger Leaping Gorge, which has a popular trekking route on the other side. In this gorge, the Jinsha (upper Yangtze) River descends dramatically between Jade Dragon and Haba Snow Mountain.

In 1938, an expedition led by the Australian lawyer, feminist, conservationist, and mountaineer, Marie Byles, failed to reach the summit due to bad weather. Bitterly disappointed by this failure, she became a follower of Buddhist thought as a consequence.

Shanzidou has been climbed only once, on May 8, 1987, by an American expedition. The summit team comprised Phil Peralta-Ramos and Eric Perlman. They climbed snow gullies and limestone headwalls, and encountered high avalanche danger and sparse opportunities for protection.>>

Nice photo. It got me to thinking. What would Earth look like in the Martian sky? Has NASA turned their cameras to take a photo? Earth being some 40% bigger than Mars, it would presumably be bigger than this. But like Venus to Earth, Earth would be an inferior planet so would only be an evening or morning star in Mars' sky. Also does it also get meteor showers? Since Mars is in a different orbit, the meteor showers would also be unrelated to Earth's showers, but does Mars also get some shooting stars?

Yes, the Earth-Moon system has been imaged from Mars. With the cameras available, they're still only unresolved points, however.

Mars gets meteor showers the same as Earth does. But yes, they are from different debris streams (although the Halley debris stream also intersects Mars's orbit). At least one meteor has been imaged from the Martian surface, and is probably not a sporadic, but is associated with a comet, and is therefore seen as a shower member.
