## Why It Matters
Cosmos 1720 serves as a specific historical data point within the extensive Soviet "Kosmos" program, which comprised over 2,000 satellites launched between 1962 and the present day. Its significance lies in its role as a component of the Strela-1M constellation, a series of Soviet satellites typically associated with communications and military operations during the Cold War era.

The entry is notable for the precision of its tracking data. With a confirmed COSPAR ID (1986-002E) and a precise launch time (02:48:00), the object represents a verifiable event in the catalog of artificial objects orbiting Earth. The use of the Kosmos-3M launch vehicle—a workhorse of the Soviet and later Russian space programs—highlights the standard deployment methods utilized for satellite constellations during the mid-1980s. By logging this specific launch from Plesetsk Cosmodrome Site 132, space historians and orbital analysts can accurately map the density and timeline of Soviet space activities during this period.

## Notable For
- **Strela-1M Classification:** Identified specifically as part of the Strela-1M series.
- **Mid-80s Launch Activity:** Represents a launch event early in the year 1986.
- **Plesetsk Infrastructure:** Utilized Site 132 at the Plesetsk Cosmodrome.
- **Orbital Tracking:** Possesses a unique Wolfram Language entity code (`Entity["Satellite", "16453"]`), facilitating its identification in computational knowledge bases.
