For example, by referring to The Nininger Collection of Meteorites catalog published in 1950 I am able to determine that a 462-gram iron in my own collection bearing the number 34.3034 is a Canyon Diablo ("34") and was example number 3,034 of that meteorite in his inventory. Such a ...

“We give a definitive answer that meteorite impact vaporization is the dominant process that creates the lunar atmosphere,” says the study’s lead author, Nicole Nie, an assistant professor in MIT’s Department of Earth, Atmospheric and Planetary Sciences. “The moon is close to 4.5 billion y...
determine the telescope's field of view: apparent - how much of the sky, in degrees, is seen edge-to-edge through the eyepiece alone (specified on the eyepiece; true or real - how much of the sky can be seen when that eyepiece is placed in the telescope (true field = apparent field...

There are many different types, sizes, and locations of rocks that orbit around the Sun. The largest rocks we call planets, and they're fairly each to spot, it is estimated that about 15,000 tons of debris from space enters the Earth's atmosphere every year....

The general conclusion of the chapter is, that escape processes strongly shape the evolution of the exoplanets and determine, if the planet loses its atmosphere due to erosion processes or, on the contrary, stays as mini-Neptune type ... KG Kislyakova,M Holmstrm,H Lammer,... 被引量: 0发...
The research team wanted to determine the feasibility for a knocked-off piece of the moon to get into this quasi-satellite orbit — a phenomenon that is quite unlikely, Malhotra said. Moon fragments that have enough kinetic energy to escape the Earth-moon system usually have too ...
