No. Comets are usually a few thousand feet to a few miles wide. An object smaller than a sand grain would not be visible in space.
Meteors which enter the earth's atmosphere are often sand grain sized, but the once we can see are usually from pebble sized objects.

Is microbe as small as a grain of a sand?

Microbes are generally much smaller than a grain of sand. While a grain of sand typically measures around 0.5 to 2 millimeters in diameter, most microbes, such as bacteria and viruses, range from about 0.2 micrometers to several micrometers in size. This means that countless microbes can fit within the space of a single grain of sand.


Are meteoroids smaller than comets but larger than asteroids?

Meteoroids are smaller than both comets and asteroids. They are small rocky or metallic objects that are typically smaller than asteroids and comets, which are large bodies that can range in size from several meters to hundreds of kilometers in diameter.


How large (in kilometers) are comets asteroids and metoroids?

Comets typically range from a few kilometers to tens of kilometers in diameter, while asteroids can vary widely, from less than a kilometer to over 1,000 kilometers across. Meteoroids are generally smaller, usually ranging from a grain of sand up to about a meter in size. Overall, the sizes of these celestial bodies can differ significantly based on their classification and individual characteristics.


Are atoms larger than a grain of sand?

If the sand is totally silicon dioxide and is assumed to be a uniform volume of one cubic millimeter then the number would be approximately 2*10^19 molecules, or 20,000,000,000,000,000,000


Are comets like planets?

No. Comets are much smaller than planets, are irregular in shape, and have highly eccentric orbits.
