About 1.3 million years ago the object may have passed within a distance of 0.16 parsecs (0.52 light-years) to the nearby star TYC 4742-1027-1, but its velocity is too high to have originated from that star system, and it probably just passed through the system's Oort cloud at a relative speed of about 15 km/s (34,000 mph; 54,000 km/h).
ʻOumuamua was at first thought to be traveling too fast for any existing spacecraft to reach. [9] [10] The Initiative for Interstellar Studies (i4is) launched Project Lyra to assess the feasibility of a mission to ʻOumuamua. [4] Several options for sending a spacecraft to ʻOumuamua within a time-frame of 5 to 25 years were suggested. [11] [12]

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.

Typical scanning speed of an audio compact disc; the speed of signals (action potentials) traveling along axons in the human cortex. 1–1.5: 3.6–5.4: 2.2–3.4: 3.3–5.0 × 10 −9: Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run. 2.39: 8.53: 5 ...

When "Webdriver Torso" is searched on Google, the Google logo will look like a Webdriver Torso video. However, if a Google Doodle is running, it will sometimes not appear. In the Android L developer builds, the Android Version Easter Egg is a reference to Webdriver Torso videos. [20]
