Dubhe
Dubhe, also called Alpha Ursae Majoris, Latinised from α Ursae Majoris, is, despite being designated "α" (alpha), the second-brightest object in the northern constellation of Ursa Major. HIP 56948 and Dubhe are Henry Draper Catalogue objects and Hipparcos objects.
Harlan J. Smith Telescope
The Harlan J. Smith Telescope is a telescope located at the McDonald Observatory, in Texas, in the United States.

Henry Draper Catalogue
The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts, which gave classifications for 86,933 more stars. HIP 56948 and Henry Draper Catalogue are Henry Draper Catalogue objects.

Hot Jupiter
Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (.
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
Lithium
Lithium is a chemical element; it has symbol Li and atomic number 3.
Main sequence
In astronomy, the main sequence is a classification of stars which appear on plots of stellar color versus brightness as a continuous and distinctive band.
See HIP 56948 and Main sequence
McDonald Observatory
McDonald Observatory is an astronomical observatory located near unincorporated community of Fort Davis in Jeff Davis County, Texas, United States.

Milky Way
The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
NBC News
NBC News is the news division of the American broadcast television network NBC.
New Scientist
New Scientist is a popular science magazine covering all aspects of science and technology.

Planetary habitability
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life.
See HIP 56948 and Planetary habitability
Polaris
Polaris is a star in the northern circumpolar constellation of Ursa Minor. HIP 56948 and Polaris are Henry Draper Catalogue objects and Hipparcos objects.
Rare Earth hypothesis
In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical and geological events and circumstances.
See HIP 56948 and Rare Earth hypothesis
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets.

Smithsonian Astrophysical Observatory
The Smithsonian Astrophysical Observatory (SAO) is a research institute of the Smithsonian Institution, concentrating on astrophysical studies including galactic and extragalactic astronomy, cosmology, solar, earth and planetary sciences, theory and instrumentation, using observations at wavelengths from the highest energy gamma rays to the radio, along with gravitational waves.

Solar analog
Solar-type stars, solar analogs (also analogues), and solar twins are stars that are particularly similar to the Sun.
See HIP 56948 and Solar analog
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See HIP 56948 and Stellar classification
Sun
The Sun is the star at the center of the Solar System. HIP 56948 and Sun are g-type main-sequence stars.
Terrestrial planet
A terrestrial planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate, rocks or metals.
