The Extrasolar Planets Encyclopaedia [9] is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, [10] [11] which maintains a database of all the currently known and candidate extrasolar planets, with individual "note" pages for each planet and a full list interactive catalog spreadsheet ...
While human population records in orbit developed from 1 in 1961, 2 in 1962, 4–7 in 1969, 7–11 in 1984 and 13 in 1995, [44] to 14 in 2021, 17 in 2023 [45] and 19 in 2024, [46] developing into a continues population of no less than 10 people on two space stations since 5 June 2022 (as of 2024). [47]
All 9 planets in the pre-IAU redefinition version of the Solar System: All United States spacecraft including New Horizons: With the New Horizons flyby of Pluto, the United States is the first nation to have its space probes explore all nine planets in the pre-2006 IAU redefinition version of the Solar System.

Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Mission: Mars orbiter designed to study the planet's atmosphere and geology and search for sub-surface water. [10] In 2017 the mission was extended until at least the end of 2020. [11] Launched: 2 June 2003; Destination: Mars; Arrival: 25 December 2003; Institution: ESA; Mars Reconnaissance Orbiter. Mission: the second NASA satellite orbiting Mars.
By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
Examining the rocky planets at the centre of the Solar System, Professor Cox examines new evidence about the violent creation of Mercury and the hostile atmosphere of Venus, contrasting them with the life-giving planet Earth and the barren Mars. [9] [10]
