List of objects at Lagrange points

Sun–Earth Lagrange points

Sun–Earth L₁

Past probes

• International Cometary Explorer, formerly the International Sun–Earth Explorer 3, diverted out of in 1983 for a comet rendezvous mission. Currently in heliocentric orbit. The Sun–Earth L₁ is also the point to which the Reboot ISEE-3 mission was attempting to return the craft as the first phase of a recovery mission.
• NASA's Genesis probe collected solar wind samples at from December 3, 2001, to April 1, 2004, when it returned the sample capsule to Earth. It returned briefly in late 2004 before being pushed into heliocentric orbit in early 2005.
• LISA Pathfinder was launched on 3 December 2015, and arrived at on 22 January 2016, where, among other experiments, it tested the technology needed by LISA to detect gravitational waves. LISA Pathfinder used an instrument consisting of two small gold alloy cubes.
• The Chang'e 5 orbiter

  Present probes

• The Solar and Heliospheric Observatory in a halo orbit around L1 to investigate of the outer layer of the Sun, making observations of solar wind and associated phenomena in the vicinity of L1, probing the interior structure of the Sun.
• The Advanced Composition Explorer in a Lissajous orbit
• WIND
• The Deep Space Climate Observatory, designed to image the sunlit Earth in 10 wavelengths and monitor total reflected radiation. Launched on 11 February 2015, began orbiting L₁ on 8 June 2015 to study the solar wind and its effects on Earth. DSCOVR is unofficially known as GORESAT, because it carries a camera always oriented to Earth and capturing full-frame photos of the planet similar to the Blue Marble. This concept was proposed by then-Vice President of the United States Al Gore in 1998 and was a centerpiece in his 2006 film An Inconvenient Truth.
• Aditya-L1 was successfully launched on 2 September 2023 and entered the halo orbit around the lagrange point on 6 January 2024. It is a Solar observation mission by ISRO. It will study solar atmosphere, solar magnetic storms, and their impact on the environment around the Earth.
• IMAP, launched in September 2025
• SWFO-L1, launched in September 2025
• Carruthers Geocorona Observatory, launched in September 2025

  Planned probes

• NEO Surveyor
• NEOMIR, ESA's planetary defense early warning and NEO detection space telescope

  Sun–Earth L₂

Past probes

• 2001 – 2010: NASA's Wilkinson Microwave Anisotropy Probe observed the cosmic microwave background. It was moved to a heliocentric orbit to avoid posing a hazard to future missions.
• 2003 – 2004: NASA's WIND. The spacecraft then went to Earth orbit, before heading to the point, where it remains in service.
• 2009 – 2013: The ESA Herschel Space Observatory exhausted its supply of liquid helium and was moved from the Lagrangian point in June 2013.
• 2009 – 2013: At the end of its mission ESA's Planck spacecraft was put into a heliocentric orbit and passivated to prevent it from endangering any future missions.
• 2011 – 2012: CNSA's Chang'e 2. Chang'e 2 was then placed onto a heliocentric orbit that took it past the near-Earth asteroid 4179 Toutatis.
• The CNSA Chang'e 6 orbiter
• 2013 – 2025: The ESA Gaia mission’s thrusters moved the spacecraft away from L2 on 27 March 2025 and into a stable retirement orbit around the Sun that will minimise the chance that it comes within 10 million km Earth for at least the next century.

  Present probes

• The joint Russian-German high-energy astrophysics observatory Spektr-RG
• The joint NASA, ESA and CSA James Webb Space Telescope
• The ESA Euclid mission

  Planned probes

• The NASA Nancy Grace Roman Space Telescope
• The ESA PLATO mission, which will find and characterize rocky exoplanets.
• The JAXA LiteBIRD mission.
• The ESA Advanced Telescope for High ENergy Astrophysics
• The ESA ARIEL mission, which will observe the atmospheres of exoplanets.
• The joint ESA-JAXA Comet Interceptor
• The NASA Large Ultraviolet Optical Infrared Surveyor which would replace the Hubble Space Telescope.

  Cancelled probes

• The ESA Eddington mission
• The NASA Terrestrial Planet Finder mission

  Sun–Earth L₃

• There are no known objects in this orbital location.

  Sun–Earth L₄

• Asteroid is the first discovered tadpole orbit companion to Earth, orbiting ; like Earth, its mean distance to the Sun is about one astronomical unit.
• Asteroid is the second Earth trojan, confirmed in November 2021, oscillating around in a tadpole orbit and expected to remain there for at least 4000 years, until destabilized by Venus.
• STEREO A made its closest pass to in September 2009, on its orbit around the Sun, slightly faster than Earth.
• OSIRIS-REx passed near the L4 point and performed a survey for asteroids between 9 and 20 February 2017.

  Sun–Earth L₅

• Asteroid, in a horseshoe companion orbit with Earth, is currently proximal to but at a high inclination.
• STEREO B made its closest pass to in October 2009, on its orbit around the Sun, slightly slower than Earth.
• The Spitzer Space Telescope is in an Earth-trailing heliocentric orbit drifting away c. 0.1 AU per year. In c. 2013–15 it has passed in its orbit.
• Hayabusa2 passed near during the spring of 2017, and imaged the surrounding area to search for Earth trojans on 18 April 2018.

  Planned

• Vigil, solar activity monitoring mission, collaborating with NOAA's SWFO-L1

  Earth–Moon Lagrange points

Earth–Moon L2

• THEMIS
• Chang'e 5-T1
• Queqiao relay satellite
• EQUULEUS nanosat.

  Earth–Moon L4 and L5

• Kordylewski clouds
• Future location of TDRS-style communication satellites to support satellite and further regions on the Moon.

  Past probes

• Hiten was the first spacecraft to demonstrate a low energy trajectory, passing by and to achieve lunar orbit at a very low fuel expense, compared to usual orbital techniques. Hiten did not find any conclusive increase in dust density at Lagrange points.

  Proposed objects

• Exploration Gateway Platform
• In his 1976 book The High Frontier: Human Colonies in Space Dr. Gerard O'Neill proposed the establishment of gigantic Space Islands in. The inhabitants of the L5 Society should convert lunar material to huge solar power satellites. Many works of fiction, most notably the Gundam series, involve colonies at these locations.

  Sun–Venus Lagrange points

L4

Sun–Mars Lagrange points

Sun–Mars L1

Proposed objects

• In a 2017 NASA workshop, former NASA Chief Scientist Jim Green proposed the placement of a magnetic dipole located at the Mars Lagrange orbit L₁ at about 320 R_♂, creating a partial and distant artificial magnetosphere. If constructed, the shield may allow the planet to partially restore its atmosphere and potentially enabling the terraforming of Mars.
