This comet didn’t fall into the Sun, but rather whipped around it – or at least, it would have if it had survived its journey. Like most sungrazing comets, this comet was torn apart and vaporised by the intense forces near the Sun.
The disc of the Sun is represented by the white circle in this looping animation.
Pluto’s day is 6.4 Earth days long. The dwarf planet’s largest moon, Charon, also rotates once every 6.4 days as the two worlds are tidally locked to each another. This sequence of images from the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera on NASA’s New Horizons spacecraft shows us full rotations of the two bodies.
Canadian researchers have charted a path that most likely pinpoints the very origins of 67P/Churyumov-Gerasimenko, the comet studied intensively by ESA’s Rosetta spacecraft. Western University astronomers believe that 67P is made from primordial material and relatively new to the inner parts of our solar system, having only arrived about 10,000 years ago.
