The Best Friends List: Planets


When it comes to exploring the vast universe, planets have always fascinated us. From their unique characteristics to their potential for sustaining life, planets offer a wealth of knowledge and wonder. In this article, we will delve into the concept of a “best friends list” for planets, exploring the criteria that make a planet an ideal candidate for human exploration and colonization. We will also discuss some of the most promising planets that could potentially make it onto this list.

What is a Best Friends List for Planets?

A best friends list for planets refers to a curated selection of celestial bodies that possess the most favorable conditions for human habitation and exploration. These planets are chosen based on a set of criteria that include factors such as distance from Earth, presence of water, atmosphere composition, and potential for sustaining life.

Criteria for Inclusion

When compiling a best friends list for planets, several key criteria are taken into consideration:

  • Distance from Earth: Proximity to Earth is an important factor as it affects travel time and communication delays. Planets that are relatively close to our solar system are more likely to be included on the list.
  • Presence of Water: Water is essential for life as we know it. Planets with evidence of liquid water, whether on the surface or in the form of ice, are given higher priority.
  • Atmosphere Composition: An atmosphere that is similar to Earth’s, with a suitable mix of gases, is crucial for human survival. Planets with a composition that can support human life are favored.
  • Potential for Sustaining Life: The presence of organic compounds, the right temperature range, and the absence of harmful radiation are all factors that contribute to a planet’s potential for sustaining life.

Promising Planets for the Best Friends List

While the search for habitable planets is ongoing, several candidates have emerged as potential members of the best friends list. Let’s explore some of these promising planets:

1. Kepler-452b

Kepler-452b, also known as Earth’s “cousin,” is located approximately 1,400 light-years away from us. It orbits a star similar to our Sun and is situated within the habitable zone, where conditions for liquid water are possible. With a radius about 1.6 times that of Earth, Kepler-452b offers a similar gravitational pull, making it a potential candidate for human colonization.

2. Proxima Centauri b

Proxima Centauri b is the closest known exoplanet to Earth, located just over 4 light-years away in the Proxima Centauri system. It orbits within the habitable zone of its star and has a mass similar to Earth. Although Proxima Centauri is a red dwarf star, which raises concerns about radiation exposure, further research is being conducted to determine the planet’s potential for sustaining life.


The TRAPPIST-1 system, located approximately 39 light-years away, has gained significant attention due to its seven Earth-sized planets. TRAPPIST-1e, one of the planets in this system, is situated within the habitable zone and has a similar size and mass to Earth. Its potential for having a rocky surface and an atmosphere makes it an intriguing candidate for further exploration.


1. How many planets are currently on the best friends list?

As of now, there is no official best friends list for planets. The concept is still in its early stages, and ongoing research and discoveries continue to shape our understanding of potentially habitable planets.

2. Are there any other criteria that could be considered for the best friends list?

While the criteria mentioned earlier are the primary factors for inclusion on the best friends list, other aspects such as geological stability, presence of resources, and potential for terraforming could also be taken into account.

3. How do scientists determine the potential for sustaining life on a planet?

Scientists use a combination of observations, data analysis, and computer models to assess a planet’s potential for sustaining life. They study factors such as the planet’s distance from its star, its atmosphere composition, and the presence of organic compounds.

4. Can planets not on the best friends list still be explored?

Absolutely! While the best friends list serves as a guide for prioritizing exploration and colonization efforts, it does not exclude other planets from being studied and explored. Every planet offers unique scientific insights and can contribute to our understanding of the universe.

5. How long would it take to travel to a planet on the best friends list?

The travel time to a planet on the best friends list would depend on its distance from Earth and the propulsion technology available. With current technology, a journey to the closest potential candidates could take several decades or even centuries. However, advancements in space travel could significantly reduce travel times in the future.


As our understanding of the universe expands, the concept of a best friends list for planets becomes increasingly relevant. By considering factors such as distance from Earth, presence of water, atmosphere composition, and potential for sustaining life, scientists can identify the most promising candidates for human exploration and colonization. While planets like Kepler-452b, Proxima Centauri b, and TRAPPIST-1e show potential, ongoing research and discoveries will continue to shape our understanding of the best friends list. Regardless of their inclusion on the list, every planet offers valuable insights and contributes to our quest for knowledge in the vast expanse of space.
