There are 2 comets Scotti out there, both short period comets (which means they orbit the sun in orbits that take less than 200 years, actually 11.5 years for one, just over 7 years for the other). Neither of them get particularly close to the sun (4 AU for one, 2.5 AU for the other - an AU is the mean distance of Earth from the sun, 93 million miles or 150 million kilometers). Neither will get particularly bright either, probably at best between about 16th and 20th magnitude (the faintest you can see with the unaided eye is about 6th magnitude and each magnitude is about 2.5 times fainter so it would take a decent telescope to see....).
