What weight class does a CubeSat belong to?

A CubeSat typically belongs to the weight class defined by the range of 1 to 10 kilograms (approximately 2.2 to 22 lbs). The designation of CubeSat as a small satellite is particularly based on its compact form factor and relatively light weight, which is tailored for educational, research, and commercial purposes. This format allows for cost-effective development and launch to low Earth orbit.

The correct selection corresponds to this established classification where CubeSats, especially the most common sizes (1U, 2U, 3U, etc.), are designed to be lightweight for efficient deployment. This has implications for their launch costs, operational capabilities, and versatility in applications like Earth monitoring, deep space exploration, and technology demonstrations. The other choices represent different weight categories that do not align with the established classifications of CubeSats, thus clarifying why they are not suitable.
