  2. Escape velocity - Wikipedia

    en.wikipedia.org/wiki/Escape_velocity

    In celestial mechanics, escape velocity or escape speed is the minimum speed needed for an object to escape from contact with or orbit of a primary body, assuming: Ballistic trajectory - no other forces are acting on the object, including propulsion and friction; No other gravity-producing objects exist.

  3. Escape Velocity (video game) - Wikipedia

    en.wikipedia.org/wiki/Escape_Velocity_(video_game)

    Escape Velocity is a single-player role-playing space trading and combat video game series first introduced in 1996 by Ambrosia Software for the Macintosh.Two other similar games based on the original, EV Override and Escape Velocity Nova, followed in 1998 and 2002 respectively, the latter of which is also available on Microsoft Windows.

  4. List of artificial objects leaving the Solar System - Wikipedia

    In order to leave the Solar System, the probe needs to reach the local escape velocity. Escape velocity from the sun without the influence of Earth is 42.1 km/s. In order to reach this speed, it is highly advantageous to use as a boost the orbital speed of the Earth around the Sun, which is 29.78 km/s.

  5. Atmospheric escape - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_escape

    One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.

  6. Event horizon - Wikipedia

    en.wikipedia.org/wiki/Event_horizon

    One of the best-known examples of an event horizon derives from general relativity's description of a black hole, a celestial object so dense that no nearby matter or radiation can escape its gravitational field. Often, this is described as the boundary within which the black hole's escape velocity is greater than the speed of light.

  7. Longevity escape velocity - Wikipedia

    en.wikipedia.org/wiki/Longevity_escape_velocity

    "The first 1000-year-old is probably only ~10 years younger than the first 150-year-old."–Aubrey de Grey, 2005 [1]. In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity [2] or biological escape velocity [3] is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing.

  9. Escape Velocity Nova - Wikipedia

    en.wikipedia.org/wiki/Escape_Velocity_Nova

    Escape Velocity Nova (a.k.a. EV Nova or EVN) is a video game developed by Ambrosia Software in collaboration with ATMOS. It is the third game in the Escape Velocity series of space trading and combat games. It was released on March 19, 2002 for Mac OS X and Mac OS 9, and later ported to Windows and released on July 11, 2003.
