Sunspots appear on the surface of the Sun, specifically in the photosphere. These darker, cooler areas are caused by magnetic activity on the Sun's surface. Sunspots can vary in size and shape and are often seen in groups.
The darkened area of a sunspot is called the umbra. It is the central region of a sunspot where the magnetic field is strongest, causing the area to appear darker compared to the surrounding photosphere of the Sun.
A small sunspot is called a plage. Plages are regions on the Sun's surface that appear brighter than their surroundings due to intense magnetic activity.
An example of a sunspot is the group of dark spots visible on the Sun's surface, caused by intense magnetic activity. Sunspots appear darker than their surrounding regions due to their lower surface temperatures. They usually occur in regions of strong magnetic fields on the solar surface.
Sunspots are most frequent about 30 degrees north or south of the equator. They tend to appear there around the maximum of the 11 year sunspot cycle. Earlier in the cycle they areseen at higher latitudes and later they are at lower latitudes.
Sunspot maximum and sunspot minimum are the points in time (roughly 6 years apart) when the sun is producing the most, or the least sunspots. In the past this has been measured both by sunspot area and sunspot count and is directly tied to the solar magnetic cycle.

No, the entire sun would not appear black if it were the same temperature as a sunspot. Sunspots appear darker because they are cooler regions on the sun's surface, not because of their temperature alone. The sun would still emit light across other wavelengths, making it visible even at the temperature of a sunspot.

Sunspots, as the name suggests, appear on the Sun or on stars - not on planets.
One doesn't have a sunspot, as a sunspot is a phenomenon that occurs on the face of the sun itself. When looked at, there appear to be black spots or marks on the sun where no light is emanating. This is caused by intense magnetic fields which inhibit convection.

Sunspots are actually the colder regions on the sun's surface, due to which comparatively less radiations are emitted by these regions than the rest of the surface of the sun. That is why they appear to be black.
Well, a sunspot is not really dark but it is at a lower temperature than the surrounding gases on the surface of the Sun. So it only looks dark by contrast with the area round it.
