•  4179 Toutatis

  4179 Toutatis/1989 AC is an Apollo, Alinda, and Mars-crosser asteroid with a chaotic orbit produced by a 3:1 resonance with the planet Jupiter and 1:4 resonance with the planet Earth. Due to its very low orbital inclination (0.47°) and its orbital period of very nearly 4 years, Toutatis makes frequent close approaches to Earth, with a currently minimum possible distance (Earth MOID) of just 0.006 AU (2.3 times as far as the Moon).

•  List of Apollo asteroids

  The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, the first asteroid of this group to be discovered by Karl Wilhelm Reinmuth. They are Earth-crosser asteroids that have orbital semi-major axes greater than that of the Earth and a perihelion distance (q) < 1.017 AU. Some can get very close to the Earth, making them a potential threat to our planet (the closer their semi-major axis is to Earth's, the less eccentricity is needed for the orbits to cross).

•  (89959) 2002 NT7

  (89959) 2002 NT7 is a near-Earth object (NEO) that became the first object observed by NASA's NEO program to be assigned a positive rating on the Palermo Technical Impact Hazard Scale for a potential impact date of February 1, 2019. Despite inflammatory press reports, the object has a "low probability" of impact, approximately one in a million. Further observations of the object have since re-rated the threat lower.

•  (29075) 1950 DA

  (29075) 1950 DA is a near Earth asteroid. It is notable for having the highest known probability of impacting Earth (although this probability remains low). For a few days in December 2004 it was temporarily surpassed by 99942 Apophis and in November 2008 the much smaller object 2008 TC3 briefly had a higher probability of impact (TC3 then impacted the Earth).

•  2003 QQ47

  2003 QQ47 is an asteroid which became famous briefly upon its discovery in late August 2003 when media outlets played up a preliminary report that it had a 1:250,000 chance of colliding with Earth on March 21, 2014. A NASA spokesman said, "Newly discovered asteroid 2003 QQ47 has received considerable media attention over the last few days because it had a small chance of colliding with the Earth in the year 2014 and was rated a "1" on the Torino Impact Hazard Scale, which goes from 0 to 10.

•  2004 AS1

  2004 AS1, also known by the temporary name AL00667, is a near-Earth asteroid, first discovered on January 13, 2004, by the LINEAR project. Although rather ordinary, it caused some controversy in astronomical circles due to initial projections posted on the web by the Minor Planet Center (MPC) suggesting an imminent collision with Earth on or about January 15 with a likelihood of 1:4.

•  1620 Geographos

  The asteroid 1620 Geographos was discovered on September 14, 1951 at the Palomar Observatory by Albert Wilson and Rudolph Minkowski. It was originally given the provisional designation 1951 RA. Its name is attributed to the Greek word which means "geographer" (Geo = Earth, graphos = drawer/writer), and was chosen to honour the National Geographic Society, and Geographers. Geographos is a Mars-crosser asteroid and a near-Earth object belonging to the Apollos.

•  2063 Bacchus

  The Apollo, Venus- and Mars-crosser asteroid 2063 Bacchus was discovered on April 24, 1977 by Charles T. Kowal at the Palomar Observatory. In March 1996 radar observations of the asteroid were conducted at the Goldstone Observatory under the direction of JPL scientists Steven Ostro and Lance Benner, allowing the construction of a model of the object . Optical observations were conducted by Petr Pravec, Marek Wolf, and Lenka Šarounová during March and April 1996.

•  1998 KY26

  The asteroid 1998 KY26 was discovered on June 2, 1998 by Spacewatch and observed until June 8 when it passed 800,000 kilometers (half a million miles) away from Earth (a little more than twice the Earth-Moon distance). It is roughly spherical and is only about 30 metres (98 ft) in diameter. Although it is nearly small enough be classified a meteoroid, the most common definition uses a diameter of 10 m as the demarcation making 1998 KY26 an asteroid rather than a meteroid.

  (35396) 1997 XF11 is a near-Earth and Mars-crosser asteroid which, shortly after its discovery on December 6, 1997, by James V. Scotti of the University of Arizona's Spacewatch Project, was predicted to make an exceptionally close approach to Earth in October 2028.

•  Electronic amplifier

  An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In this sense, an amplifier may be considered as modulating the output of the power supply.
