... The chemical composition of a lunar atmosphere temporarily produced by comet impact is studied during day and night. C-rich and long-period comets are insufficient sources of water ice on the Moon. ... An observable amount of polar hydrogen can be delivered to the Moon by single impact of O-rich short-period comet with diameter of 5 km in the form of water ice. ... Thermal stability of SO 2 and CO 2 ices at the poles of the Moon Comets are important sources of lunar polar volatiles. ...

... That star is called Sirius, and it is the brightest star in Earth's nighttime sky. ... But the other reason Sirius is so brilliant in our nighttime sky is that it is so close; Sirius is the nearest neighbor star to the Sun that can be seen with the unaided eye from the Northern Hemisphere. ... and even the nearest other star (alpha Centauri, visible from the Southern Hemisphere) would be 6,000 miles away. ...
