What is a Astronomical Unit and a Versta?
An astronomical unit is a unit of length roughly equal to the average distance between Earth and the Sun. It is defined as exactly 149,597,870,700 meters.
The Versta (Russian: верста́, plural: вёрсты, vyorsty) is an obsolete Russian unit of length or distance. It was defined as being equal to 500 sazhenes (саже́нь).
Based on the standardized sajene of 7 English feet (2.1336 meters) established under Peter the Great, one Versta is equal to:
- 1066.8 meters (m)
- 1.0668 kilometers (km)
- Approximately 3500 feet (ft)
- Approximately 0.6629 miles (mi)
Note: The Astronomical Unit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Versta belongs to the imperial/US customary system.
History of the Astronomical Unit and Versta
Historically used to measure distances within the Solar System, its value was refined over centuries through astronomical observations. The exact definition was adopted by the IAU in 2012.
The Versta was a traditional unit of distance in Russia, used since at least the 11th century. Its length varied historically until Peter the Great standardized the Russian system of measures in the 18th century, linking the sajene to the English foot (1 sajene = 7 feet). This fixed the Versta at 500 * 7 = 3500 feet, or 1066.8 meters.
- Imperial Russia: The Versta became the standard unit for measuring road distances throughout the Russian Empire. Roads were often marked with verst posts (верстово́й столб, verstovoy stolb) indicating distances.
- Mezhevaya Versta: A less common "boundary versta" (межева́я верста́, mezhevaya versta) also existed, primarily for land surveying. It was twice as long, equal to 1000 sazhenes (approximately 2.13 km). Unless specified otherwise, "Versta" usually refers to the standard 500-sajene unit.
- Metrication: The Versta became obsolete after the Russian Revolution. The metric system was officially adopted in 1918 and became mandatory in 1925, replacing the traditional Russian units.
Common Uses for astronomical units and versts
Explore the typical applications for both Astronomical Unit (imperial/US) and Versta (imperial/US) to understand their common contexts.
Common Uses for astronomical units
- Measuring distances within the Solar System (e.g., planet orbits)
- Expressing distances to near-Earth objects
Common Uses for versts
The Versta was primarily used for:
- Measuring Travel Distances: It was the standard unit for road distances between towns and cities in Imperial Russia. Maps, travel guides, and road markers all used Versts.
- Postal System: Distances for mail delivery and stagecoach routes were measured in Versts.
- Literature: The Versta frequently appears in Russian literature of the 18th and 19th centuries (e.g., works by Pushkin, Gogol, Tolstoy, Chekhov) to describe journeys and distances, adding historical context.
- Military: Used for measuring marching distances and geographical surveys.
Its use today is purely historical or literary.
Frequently Asked Questions
Questions About Astronomical Unit (AU)
Why use Astronomical Units instead of kilometers or miles?
Astronomical Units (AU) provide a more convenient scale for the vast distances within our solar system. Expressing interplanetary distances in km or miles results in extremely large and unwieldy numbers.
How many kilometers/miles is 1 AU?
1 Astronomical Unit (AU) is approximately 149.6 million kilometers or 93 million miles.
How long does it take light to travel 1 AU?
It takes sunlight approximately 8 minutes and 20 seconds to travel the distance of one Astronomical Unit from the Sun to the Earth.
About Versta (versta)
How long is a Versta?
A standard Versta is exactly:
- 1066.8 meters
- 1.0668 kilometers
- Approximately 0.6629 miles
- Approximately 3500 feet
- Exactly 500 sazhenes
What were the main related Russian units?
The Versta was part of the Imperial Russian system of measures:
- 1 Versta = 500 Sajenes (саже́нь)
- 1 Sajene = 3 Arshins (арши́н) ≈ 2.13 m / 7 ft
- 1 Arshin = 16 Vershoks (вершо́к) ≈ 71.1 cm / 28 in
- 1 Vershok ≈ 4.445 cm / 1.75 in
Was there more than one type of Versta?
Yes, besides the standard "travel" Versta (500 sazhenes), there was a Mezhevaya Versta ("boundary versta") used for land surveying, which was equal to 1000 sazhenes (about 2.13 km). The 500-sajene Versta was far more common.
Is the Versta still used today?
No, the Versta is obsolete. It was officially replaced by the kilometer and meter when Russia adopted the metric system in the early 20th century (mandatory from 1925). Its use is now confined to historical contexts and literature.
How does a Versta compare to a kilometer or a mile?
- A Versta is slightly longer than a kilometer: 1 Versta ≈ 1.07 km.
- A Versta is significantly shorter than a mile: 1 Versta ≈ 0.66 miles (roughly two-thirds of a mile). Conversely, 1 mile ≈ 1.51 Versts.
Is the Versta an SI unit?
No, the Versta is not an SI unit. It is a traditional unit from the historical Russian system of measurement. The SI base unit for length is the meter (m).
