What NASA Discovered When They Landed On A Comet
What is Comet ?
Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet’s orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of miles. There are likely billions of comets orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud.
The current number of known comets is: 3,743
Humankind has made space exploration one of our main goals for over 70 years now, and many milestones have been achieved since then, including the first landing on the Moon, the first serviceable space telescope, and even landing on a comet.
