44 Closest Stars and How They Compare to our Sun

Humans have been fascinated by the stars in the night sky since the dawn of time.

We’ve been decoding the mysteries of celestial bodies for many centuries, but it is only in the last 200 years or so that we’ve been able to glean more detailed information on the lights that dot the night sky. Friedrich Bessel’s method of stellar parallax was a breakthrough in accurately measuring the positions of stars, and opened new doors in the effort to map our universe. Today, high-powered telescopes offer even more granular data on our cosmic neighborhood.

The infographic above, from Alan’s Factory Outlet, categorizes the 44 closest stars to Earth, examining the size, luminosity, constellations, systems, and potential planets of each star.

Our Nearest Stellar Neighbors

Our closest neighboring stars are all part of the same solar system: Alpha Centauri. This triple star system – consisting of Proxima Centauri, Alpha Centauri A, and Alpha Centauri B – attracts a lot of interest because it hosts planets, including one that may be similar to Earth.

The planet, Proxima Centauri b, is a lot closer to its star than Earth is to the Sun. However, because Proxima Centauri is a smaller and cooler red dwarf type star, the planet’s orbit is within the habitable zone. It’s thought that Proxima Centauri b receives approximately the same amount of solar energy as Earth does from our Sun.

Here’s a full list of the 44 of the closest stars to Earth:

Even though we see many of these stars in the night sky, humans aren’t likely to see them in person any time soon. To put these vast distances into perspective, if the Voyager spacecraft were to travel to Proxima Centauri, it would take over 73,000 years to finally arrive.

The Brightest Stars in the Sky

The closest stars aren’t necessarily the ones most visible to us here on Earth. Here are the top 10 stars in terms of visual brightness from Earth:

10AchernarEridanus0.46 (0.40–0.46var)139.0

Excluding our Sun, the brightest star visible from Earth is Sirius, or the Dog Star. Sirius, which is about 25 times more luminous than the sun, visually punctuates the constellation Canis Major.

Filling in the Gaps

The next step in learning more about our surroundings in the cosmos will be seeing which of the stars listed above have planets orbiting them. So far, the 44 stars in the infographic have over 40 planets scattered among them, though new discoveries are made all the time.

With each new mission and discovery, we learn a little bit more about our pocket of the universe.

Visualized: A Global Risk Assessment of 2021 And Beyond

Which risks are top of mind in 2021? We visualize the World Economic Forum’s risk assessment for top global risks by impact and livelihood.

Visualized: A Global Risk Assessment of 2021 And Beyond

Risk is all around us. After the events of 2020, it’s not surprising that the level and variety of risks we face have become more pronounced than ever.

Every year, the World Economic Forum analyzes the top risks in the world in its Global Risks Report. Risks were identified based on 800+ responses of surveyed leaders across various levels of expertise, organizations, and regional distribution.

Which risks are top of mind in 2021?

The World’s Top Risks by Likelihood and Impact

According to WEF’s risk assessment methodology, all the global risks in 2021 fall into the following broad categories:

  • 🔵 Economic
  • 🟢 Environmental
  • 🟠 Geopolitical
  • 🔴 Societal
  • 🟣 Technological

It goes without saying that infectious diseases have now become one of the top societal risks on both metrics of likelihood and impact.

That said, environmental risks continue to dominate the leaderboard, accounting for five of the top 10 risks by impact, especially when it comes to climate action failure.

Several countries are off-track in meeting emissions goals set by the Paris Climate Agreement in 2015, while the pandemic has also delayed progress in the shift towards a carbon-neutral economy. Meanwhile, biodiversity loss is occurring at unprecedented rates.

RankTop Risks by LikelihoodTop Risks by Impact
#1🟢Extreme weather🔴Infectious diseases
#2🟢Climate action failure🟢Climate action failure
#3🟢Human environmental damage🟠Weapons of mass destruction
#4🔴Infectious diseases🟢Biodiversity loss
#5🟢Biodiversity loss🟢Natural resource crises
#6🟣Digital power concentration🟢Human environmental damage
#7🟣Digital inequality🔴Livelihood crises
#8🟠Interstate relations fracture🟢Extreme weather
#9🟣Cybersecurity failure🔵Debt crises
#10🔴Livelihood crises🟣IT Infrastructure breakdown

As for other risks, the prospect of weapons of mass destruction ranks in third place for potential impact. In the global arms race, a single misstep would trigger severe consequences on civil and political stability.

New Risks in 2021

While many of the risks included in the Global Risks Report 2021 are familiar to those who have read the editions of years past, there are a flurry of new entries to the list this year.

Here are some of the most interesting ones in the risk assessment, sorted by category:

Societal Risks

COVID-19 has resulted in a myriad of knock-on societal risks, from youth disillusionment and mental health deterioration to livelihood crises. The first two risks in particular go hand-in-hand, as “pandemials” (youth aged 15-24) are staring down a turbulent future. This generation is more likely to report high distress from disrupted educational and economic prospects.

At the same time, as countries prepare for widespread immunization against COVID-19, another related societal risk is the backlash against science. The WEF identifies vaccines and immunization as subjects susceptible to disinformation and denial of scientific evidence.

Economic Risks

As monetary stimulus was kicked into high gear to prop up markets and support many closed businesses and quarantined families, the economic outlook seems more fragile than ever. Debt-to-GDP ratios continue to rise across advanced economies—if GDP growth stagnates for too long, a potential debt crisis could see many businesses and major nations default on their debt.

With greater stress accumulating on a range of major industries such as travel and hospitality, the economy risks a build-up of “zombie” firms that drag down overall productivity. Despite this, market valuations and asset prices continue to rise, with equity markets rewarding investors betting on a swift recovery so far.

Technological Risks

Last but not least, COVID-19 has raised the alert on various technological risks. Despite the accelerated shift towards remote work and digitalization of entire industries, the reality is that digital inequality leaves those with lower digital literacy behind—worsening existing inequalities.

Big Tech is also bloating even further, growing its digital power concentration. The market share some companies hold in their respective sectors, such as Amazon in online retail, threatens to erode the agency of other players.

Assessing the Top 10 Risks On the Horizon

Back in mid-2020, the WEF attempted to quantify the biggest risks over an 18-month period, with a prolonged economic recession emerging on top.

In this report’s risk assessment, global risks are further classified by how soon their resulting threats are expected to occur. Weapons of mass destruction remain the top risk, though on a much longer scale of up to 10 years in the future.

RankRisk%Time Horizon
#1🟠Weapons of mass destruction62.7Long-term (5-10 years)
#2🔴Infectious diseases58Short-term risks (0-2 years)
#3🔴Livelihood crises55.1Short-term risks (0-2 years)
#4🔵Asset bubble burst53.3Medium-term risks (3-5 years)
#5🟣 IT infrastructure breakdown53.3Medium-term risks (3-5 years)
#6🔵Price instability52.9Medium-term risks (3-5 years)
#7🟢Extreme weather events52.7Short-term risks (0-2 years)
#8🔵Commodity shocks52.7Medium-term risks (3-5 years)
#9🔵Debt crises52.3Medium-term risks (3-5 years)
#10🟠State collapse51.8Long-term (5-10 years)

Through this perspective, COVID-19 (and its variants) remains high in the next two years as the world scrambles to return to normal.

It’s also clear that more economic risks are taking center stage, from an asset bubble burst to price instability that could have a profound effect over the next five years.

Visualizing Countries by Share of Earth’s Surface

There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.

Today’s visualization uses data primarily from the United Nations Statistics Division (UNSD) to rank the world’s countries by their share of Earth’s surface.

Breakdown of Countries Share of Earth’s Surface

The largest countries by surface area are Russia (3.35%), Canada (1.96%), and China (1.88%).

Together they occupy roughly 7.2% of Earth’s surface. Russia is so big that even if we divided the country between its Asian and European sections, those new regions would still be the largest in their respective continents.

Antarctica, although not a country, covers the second largest amount of land overall at 2.75%. Meanwhile, the other nations that surpass the 1% mark for surface area include the United States (1.87%), Brazil (1.67%), and Australia (1.51%).

The remaining 195 countries and regions below 1%, combined, account for the other half of Earth’s land surface. Among the world’s smallest countries are the island nations of the Caribbean and the South Pacific Ocean. However, the tiniest of the tiny are Vatican City and Monaco, which combine for a total area of just 2.51 km².

The remaining 70% of Earth’s surface is water: 27% territorial waters and 43% international waters or areas beyond national jurisdiction.

Areas Beyond National Jurisdiction

In the past, nations adhered to the freedom-of-the-seas doctrine, a 17th century principle that limited jurisdiction over the oceans to a narrow area along a nation’s coastline. The rest of the seas did not belong to any nation and were free for countries to travel and exploit.

This situation lasted into the 20th century, but by mid-century there was an effort to extend national claims as competition for offshore resources became increasingly fierce and ocean pollution became an issue.

In 1982, the United Nations adopted the Law of the Sea Convention which extended international law over the extra-territorial waters. The convention established freedom-of-navigation rights and set territorial sea boundaries 12 miles (19 km) offshore with exclusive economic zones up to 200 miles (322 km) offshore, extending a country’s influence over maritime resources.

Does Size Matter?

The size of countries is the outcome of politics, economics, history, and geography. Put simply, borders can change over time.

In 1946, there were 76 independent countries in the world, and today there are 195. There are forces that push together or pull apart landscapes over time. While physical geography plays a role in the identity of nations, Sheikh Zayed bin Sultan Al Nahyan, the former ruler of UAE, a tiny Gulf nation, put it best:

“A country is not measured by the size of its area on the map. A country is truly measured by its heritage and culture.”
