The cratered surface of a large body is shown: Mercury. The largest feature visible is a large impact crater with two rings, near the image center. Arms from the BepiColumbo spacecraft that took the image are seen extending into the image from the top and the right. Please see the explanation for more detailed information.
图中显示的是一颗大型天体的陨石坑表面：水星。可见的最大特征是靠近图像中心有大型双环陨石坑。拍摄该图像的贝比科隆博号航天器的机械臂从顶部和右侧延伸到图像中。有关更多详细信息，请参阅说明。
2022年6月28日 Mercury from Passing BepiColombo Image Credit & License: ESA, JAXA, BepiColombo, MTM Explanation: Which part of the Moon is this? No part — because this is the planet Mercury. Mercury’s old surface is heavily cratered like that of Earth’s Moon. Mercury, while only slightly larger than Luna, is much denser and more massive than any Solar System moon because it is made mostly of iron. In fact, our Earth is the only planet more dense. Because Mercury rotates exactly three times for every two orbits around the Sun, and because Mercury’s orbit is so elliptical, visitors on Mercury could see the Sun rise, stop in the sky, go back toward the rising horizon, stop again, and then set quickly over the other horizon. From…
2020 May 4 Earth Flyby of BepiColombo Image Credit & License: ESA, BepiColombo, MTM Explanation: What it would look like to approach planet Earth? Such an event was recorded visually in great detail by ESA’s and JAXA’s robotic BepiColombo spacecraft last month as it swung back past Earth on its journey in to the planet Mercury. Earth can be seen rotating on approach as it comes out from behind the spacecraft’s high-gain antenna in this nearly 10-hour time-lapse video. The Earth is so bright that no background stars are visible. Launched in 2018, the robotic BepiColombo used the gravity of Earth to adjust its course, the first of nine planetary flybys over the next seven years — but the only one involving Earth. Scheduled to…
