Comet C/2019A Q4 Borisov, discovered on August 29, 2019, has astronomers intrigued as it is only the second known object to be have an orbit and velocity that suggests it is of interstellar origin. It’s orbit has an eccentricity of about 3.5. It will reach perihelion on December 7, 2019.

ESA’s Rosetta mission has concluded with a controlled descent into Comet 67P/Churyumov–Gerasimenko. “The descent gave Rosetta the opportunity to study the comet’s gas, dust and plasma environment very close to its surface, as well as take very high-resolution images… after becoming the first spacecraft to orbit a comet, and the first to deploy a lander, Philae, in November 2014.” More
Rosetta’s OSIRIS camera team has launched a new website to showcase their recent images of Comet 67P/Churyumov–Gerasimenko.

ESA’s Rosetta spacecraft made the first in situ detection of oxygen molecules outgassing from a comet, an unexpected observation that challenges current Solar System formation models. More
After nearly a decade-long journey, NASA’s New Horizons spacecraft has made its flyby of the Pluto and its moons.
Rosetta’s lander Philae has emerged from hibernation. Comet Lander Philae, which shut down 64 hours after the historic comet landing in November 2014, has sent back signals indicating that it is in good health.
In the 64 hours before the Philae comet lander went into hibernation, it conducted experiments, deployed all 10 instruments, and returned data that is now being analysed. More
ESA’s Rosetta mission has landed its Philae lander on Comet 67P/Churyumov–Gerasimenko, marking the first time in history this has been accomplished. More

Comet C/2013 A1, also known as comet Siding Spring, will graze the planet Mars on Sunday within about 139,500 km, less than half the earth-moon distance. Spacecraft orbiting around mars are getting prepped for the encounter.
Launched in 2004, the Rosetta spacecraft has finally arrived at comet 67P/Churyumov-Gerasimenko. It will be the “first mission in history to rendezvous with a comet, escort it as it orbits the Sun, and deploy a lander to its surface”. Follow the event live at: More
As the ESA’s Rosetta spacecraft closes to within 1000 km of Comet 67P/Churyumov-Gerasimenko, the Rosetta science team has released a new image and made the first temperature measurements of the comet’s core.
