Metro stations are essential to urban life, but their quality and level of modernization vary across Europe’s capital cities.
High-quality transportation networks play a crucial role in driving business productivity by enhancing mobility and expanding access to a broader labor pool. Moreover, investment in metro systems is connected with higher foreign direct investment. These investments boost a city’s appeal by improving commuting speed and accessibility.
This graphic ranks the metro systems of European capital cities, based on data from Bounce.
Methodology
For the ranking, metro systems across 19 European capital cities were scored according to the following metrics:
- Number of stations
- Annual ridership
- Distance covered
- Google review scores
- The share of positive and negative online reactions to articles about each metro system
Due to travel advisories, Belarus, Ukraine, and Russian capitals were excluded. Overall, metro systems were measured out of a score of 10.
Norway is Home to Top Metro System in European Capitals
Oslo, the capital of Norway, tops the list with 101 metro stations across its transit network.
In 2023, it became the first metro system in the world to operate entirely on electric power. As the largest network in Scandinavia, Oslo’s metro stations earned an average Google review score of 4.13 out of 5 stars, with users often saying they were “very well organized” and “easy to get around”.

The Five Countries to Land on the Moon, and When They Did It
Key Takeaways
- Only five countries have achieved a successful soft landing on the Moon since 1966.
- The U.S. remains the only nation to land astronauts on the lunar surface.
- Several countries have reached lunar orbit or attempted landings, but only a handful have completed controlled touchdowns.
Roughly 200 countries exist today, but only five have successfully landed a spacecraft on the Moon.
Achieving a controlled lunar landing remains one of the most difficult feats in space exploration, requiring decades of engineering expertise, precision navigation, and advanced propulsion systems. While many nations have reached the Moon or attempted landings, only a select group has completed a successful soft landing.
Using data from HowStuffWorks, this map highlights the five countries that have joined this exclusive club. Russia is shown in place of the USSR, which officially dissolved in 1991.
First Successful Moon Landings: A Chronology
Each country reached the Moon during a different era of space exploration, spanning nearly six decades from the Cold War space race to today’s renewed global competition. Here’s when each nation completed its first successful soft landing:
| Year | Nation | Mission | Notes |
|---|---|---|---|
| Feb 3, 1966 | ☭ USSR | Luna 9 | Seven years after the previous Luna 2 reached the Moon (but crashed into it), Luna 9 landed and transmitted data from the lunar surface. |
| Jun 2, 1966 | 🇺🇸 United States | Surveyor 1 | Surveyor 1 landed and took over 11,000 pictures. Between 1969-1972, the U.S. then had six successful crewed missions through its Apollo program. |
| Dec 14, 2013 | 🇨🇳 China | Change'e 3 | China landed its first soft rover on the Moon. This was the world's first celestial landing since August 1976. |
| Aug 13, 2023 | 🇮🇳 India | Chandrayaan-3 | India's ISRO became the fourth space agency to land on the Moon, and the first to land at the lunar south pole. |
| Jan 19, 2024 | 🇯🇵 Japan | SLIM | Nicknamed the "Moon Sniper", Japan's entry was designed to be the first hyper-accurate Moon landing. It arrived within 100 m of its target. |
And here is a map of all 28 successful Moon landings by country:

Nearly every successful landing has occurred on the Moon’s near side, where communication with Earth is much easier. China is the only country to achieve successful soft landings on the lunar far side, with its Chang’e 4 and Chang’e 6 missions marking major milestones in robotic exploration.
The nature of lunar exploration is also changing. In 2025, Firefly Aerospace became the first privately funded company to complete a successful Moon landing with its Blue Ghost M1 mission, launched aboard a SpaceX Falcon 9 rocket.
Failed Landings and Other Missions
Even though achieving a soft, controlled landing is rare, there have been many more lunar missions by other countries.
Here are two recent missions that attempted soft landings but failed:
- 🇮🇱 Israel: The country’s Beresheet mission successfully entered lunar orbit in 2019, but ended with a crash landing.
- 🇷🇺 Russia: In its first attempt since the dissolution of the USSR, Russia’s Luna 25 mission crash landed in 2023. Russia is expected to have another go with Luna 27 in 2029-2030.
Meanwhile, several other countries and agencies have completed successful non-landing missions to the Moon, including Pakistan, Canada, Italy, the European Space Agency, and South Korea. Private companies have also become more active in lunar exploration.
Future Attempts
The race to join the Moon landing club is far from over. Several countries, along with a growing number of private companies, are developing lunar missions as governments and businesses prepare for a new era of Moon exploration tied to scientific research, resource prospecting, and future crewed missions.
Not every mission reaches the launch pad. For example, Canada’s planned lunar rover mission targeting 2029 was cancelled in March 2026, illustrating just how technically and financially challenging lunar exploration remains.

Which U.S. States Have the Most Vehicles Per 1,000 People?
Key Takeaways
- Montana has 2,174 registered vehicles per 1,000 residents, making it the only state with more than two vehicles per person.
- Great Plains states dominate the top of the ranking, with South Dakota, Wyoming, and North Dakota all above 1,300 vehicles per 1,000 people.
- The U.S. averages 875 registered highway vehicles per 1,000 people, according to 2024 federal data.
Americans have nearly 298 million registered highway vehicles, but some states have far more vehicles than residents, while others have fewer than one vehicle for every person.
This map highlights the number of registered highway vehicles in each state per 1,000 people, using official 2024 highway data sourced from the Bureau of Transportation Statistics.
The differences reflect a mix of population density, commercial fleet registrations, and the types of vehicles counted in federal registration data.
Montana: More Than Two Cars Per Person
Montana is the nation’s biggest outlier, with 2,174 registered highway vehicles per 1,000 residents. In total, the state recorded nearly 2.5 million vehicles in 2024, despite having a population of just 1.1 million people.
The following data table lists states by their per-capita vehicle rates in 2024.
| Rank | State | Vehicles Per 1,000 People |
|---|---|---|
| 1 | Montana | 2,174 |
| 2 | South Dakota | 1,518 |
| 3 | Wyoming | 1,495 |
| 4 | North Dakota | 1,357 |
| 5 | Iowa | 1,194 |
| 6 | Alabama | 1,095 |
| 7 | Arkansas | 1,087 |

| 51 | District of Columbia | 438 |
| 52 | Delaware | 426 |
Montanans do not necessarily have two to three vehicles apiece. Instead, several factors help explain how the state became such an outlier.
For one, a lack of sales tax makes the state attractive to many businesses registering commercial vehicle fleets, including businesses from outside Montana. This is especially relevant given the state’s large trucking, logging, mining, and agricultural sectors. Notably, over 60% of the vehicles on Montana’s highways are trucks.
There’s also the trailer component: livestock, RV, and utility trailers are all counted as vehicles under Federal Highway Administration (FHWA) registration. Montana had nearly as many trailers on its highways in 2024 as passenger cars.
The Great Plains and the City
Part of the Montana story is also a broader regional divide between larger, more rural states in the country’s interior and more densely populated coastal states.
States like North Dakota (1,357) and South Dakota (1,518) are characterized by smaller towns separated by longer distances, making driving, especially on highways, a practical necessity. This pattern appears across the Great Plains, including in Montana, Iowa (1,194), and Wyoming (1,495).
On the other end of the spectrum are denser, more urbanized states where people have more transportation options. For example, the Northeast corridor links cities like Boston, Baltimore, and Philadelphia through passenger rail and other transit options, reducing the need for household vehicle ownership. The same applies in New York (1,049), where car ownership costs are high in the country’s largest city, as well as in Washington, D.C. (438).
Delaware (426), a small and heavily urbanized state, has the lowest per-capita vehicle rate in the country.
