## Summary
A femtosatellite (also known as a femtosat) is a miniaturized artificial satellite distinguished by its very small size and mass. It is classified as a specific type of spacecraft and is considered a subclass of both artificial satellites and miniature objects.

## Key Facts
*   **Definition:** A miniaturized artificial satellite of very small size and mass.
*   **Aliases:** Also referred to as a "femtosat."
*   **Classification:** It is an instance of a "spacecraft class."
*   **Hierarchy:** A subclass of "artificial satellite" (a human-made object put into orbit) and "miniature object."
*   **Sequence:** In the classification of miniaturized satellites, the femtosatellite is followed by the "picosatellite" (defined generally as a satellite less than 1 kg).
*   **Data Source:** The entity has a Google Knowledge Graph ID of `/g/12nvpxr3h`.
*   **Language Availability:** Wikipedia content for this entity is available in Polish (pl).

## FAQs
### Q: What is a femtosatellite?
A: A femtosatellite is a class of spacecraft defined by its very small size and mass. It is a miniaturized version of an artificial satellite.

### Q: How does a femtosatellite relate to a picosatellite?
A: Based on structured classifications, the femtosatellite category is followed by the picosatellite category. Picosatellites are generally defined as miniaturized artificial satellites with a mass of less than 1 kg.

### Q: What are the other names for a femtosatellite?
A: The term "femtosat" is used as an alias for femtosatellite.

### Q: Is a femtosatellite considered a real spacecraft?
A: Yes, it is an instance of a "spacecraft class" and a subclass of "artificial satellite."

## Why It Matters
The femtosatellite represents the extreme frontier of spacecraft miniaturization, pushing the boundaries of what defines a functional orbital object. As a subclass of artificial satellites and miniature objects, it signifies a shift in aerospace engineering towards drastically reduced mass and volume.

This classification matters because it creates a distinct category for satellites that are smaller than the already tiny "picosatellite" (generally under 1 kg). By defining these specific boundaries, the femtosatellite class allows engineers and researchers to categorize emerging technologies that operate with minimal resources. The existence of this classification highlights the technical capability to produce human-made objects capable of orbiting Earth while maintaining a "very small size and mass," distinguishing them from conventional, larger satellite infrastructure. This taxonomy is essential for organizing the rapid evolution of space hardware and tracking the development of increasingly compact orbital systems.

## Notable For
*   **Extreme Miniaturization:** Being defined specifically as a satellite of "very small size and mass."
*   **Specific Classification:** Serving as a distinct "spacecraft class" separate from larger small-sat categories.
*   **Nomenclature:** Possessing the specific shorthand alias "femtosat."
*   **Taxonomic Position:** Being a direct subclass of "artificial satellite" and "miniature object."

## Body
### Classification and Definition
The femtosatellite is formally classified as an instance of a **spacecraft class**. It falls under the broader umbrella of **artificial satellites**, defined as human-made objects put into orbit. Additionally, it is categorized as a **miniature object**, emphasizing its defining physical characteristic of reduced scale.

### Nomenclature
The entity is recognized under the alias **femtosat**. This shorthand is derived from the metric prefix "femto," aligning with the naming conventions of other miniaturized satellite classes, though the entity is specifically defined by its qualitative "very small size and mass."

### Relation to Other Satellites
In the hierarchy of miniaturized spacecraft, the femtosatellite is structurally linked to the **picosatellite**. Data indicates that the femtosatellite is "followed by" the picosatellite class. For context regarding the scale of this taxonomy, the picosatellite is generally described as a miniaturized artificial satellite with a mass of less than 1 kg.

### Data and Identifiers
*   **Wikidata Description:** Miniaturized artificial satellite of very small size and mass.
*   **Google Knowledge Graph ID:** `/g/12nvpxr3h`.
*   **Site Statistics:** The entity has a sitelink count of 1 and is represented in the Polish language version of Wikipedia.
