What distinguishes a small satellite from a nanosatellite?

Nanosatellites are characterized primarily by their weight, which is significantly less than that of small satellites. Typically, a nanosatellite weighs 1 to 10 kg (2.2 to 22 lbs), whereas small satellites can range in weight from 1 kg up to around 220 lbs (about 100 kg). This weight classification is critical in differentiating between the two categories of satellites.

The weight distinction reflects on the design, complexity, and capabilities of the satellites. Nanosatellites, due to their smaller size and lightweight nature, are often launched as secondary payloads on larger missions and can be designed for specific, focused tasks, usually implementing simpler systems and technology. In contrast, small satellites, while still relatively compact, can accommodate a larger array of instruments and capabilities, making them suitable for a broader range of missions.

The other statements about nanosatellites possessing more advanced sensors or being larger than small satellites do not hold true within the context of a proper classification. Similarly, the statement regarding small satellites being limited to weighing less than 220 lbs misrepresents the definitions, as small satellites can indeed weigh up to that limit, distinct from smaller nanosatellites. Thus, the distinction in weight is the primary
