* [https://en.wikipedia.org/wiki/Chicxulub_crater Chicxulub crater] says the impactor diameter ranges from 11 to 81 km. The cite is to a preprint, not a [https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources WP:RS]. 81 is likely a typo for 18. Anyway we can't use it. Most often given as 10-15 km and here is a cite<ref>
Parkos, D., Alexeenko, A., Kulakhmetov, M., Johnson, B.C. and Melosh, H.J., 2015. [https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2015JE004857 NOx production and rainout from Chicxulub impact ejecta reentry]. Journal of Geophysical Research: Planets, 120(12), pp.2152-2168{{quote| ''"Asteroids striking the Earth typically [Minton and Malhotra, 2010] have an impactor density of 2680 kg/m3and an impact velocity of 20 km/s.Assuming these properties, modern scaling relations indicate that a 10–15 km diameter projectile [Collins et al., 2008] created the 170 km diameter Chicxulub crater"''}}</ref>
* [[Wikipedia:Dew_point]] - says ''"When the temperature is below the freezing point of water, the dew point is called the frost point, as frost is formed rather than dew"'' <br />Though popular accounts of meteorology sometimes suggest this, dew point and frost point differ. Dew point is the temperature for 100% humidity of the air in normal conditions. Frost point is the higher temperature for 100% humidity over an ice surface. This distinction normally doesn't matter much, but is important for processes in clouds. Growth of icy particles is favoured over water droplets when both are possible, because the frost point is at a higher temperature than the dew point.<ref>I am summarizing there what the meteorologist Jeff Haby explains [http://www.theweatherprediction.com/habyhints/347/ here] {{quote|"The dew point is the temperature at which the air is saturated with respect to water vapor over a liquid surface. When the temperature is equal to the dewpoint then the relative humidity is 100%. The common ways for the relative humidity to be 100% is to 1) cool the air to the dewpoint, 2) evaporate moisture into the air until the air is saturated, 3) lift the air until it adiabatically cools to the dew point. <br /> "The frost point is the temperature at which the air is saturated with respect to water vapor over an ice surface. It is more difficult more water molecules to escape a frozen surface as compared to a liquid surface since an ice has a stronger bonding between neighboring water molecules. Because of this, the frost point is greater in temperature than the dew point. This fact is important to precipitation growth in clouds. Since the vapor pressure is less over an ice surface as compared to a supercooled liquid surface at the same temperature, when the relative humidity is 100% with respect to water vapor the relative humidity over the ice surface will be greater than 100%. Thus, precipitation growth is favored on the ice particles."}}</ref>▼
* [[Wikipedia:Nuclear_winter#Nuclear_summer]] Cites an article in New Scientist that doesn't seem to exist. [https://scholar.google.co.uk/scholar?hl=en&as_sdt=0%2C5&q=%22Researchers+Blow+Hot+and+Cold+Over+Armageddon%22&btnG=] and online post from 2002 that talks about increased UV not warming <ref>"Nuclear winter might give way to a nuclear summer. The high temperatures of the nuclear fireballs could destroy the ozone gas of the middle stratosphere. The result would be an increase in ultraviolet radiation on the surface of the earth, affecting both plant and animal life. "[https://web.archive.org/web/20110814051805/http://www3.wooster.edu/history/jgates/book-ch11.html]</ref> With only these two cites, and lack of details, will post to talk page suggesting "Nuclear summer" should probably be deleted due to insufficient evidence of notability.▼
* [https://en.wikipedia.org/wiki/Asteroid_impact_avoidance#Deflection_efforts Asteroid_impact_avoidance#Deflection_efforts] says ''"in addition, the warning time is '''unlikely to be more than a few months'''"'', misparaphrases source, the source used says ''"warning period for a potential impact from a long period comet '''may be as short as a year'''"''<ref>[http://space.nss.org/media/2000-Report-Of-The-Task-Force-On-Potentially-Hazardous-Near-Earth-Objects-UK.pdf Report of the Task Force onpotentially hazardous NEAR EARTH OBJECTS]</ref> <br />In other words, in the source, a year is mentioned as the likely shortest warning period, while Wikipedia summarizes it as saying that few months is likely the longest. Also the source used is from 2008, before the start of most of our modern all sky surveys. Warning periods increased since then.
* [[Wikipedia:2010_AU118]] "''NEODyS lists the nominal 20 October 2020 Earth distance as 3 AU (450,000,000 km; 280,000,000 mi).[7]''" - [https://newton.spacedys.com/neodys/index.php?pc=1.1.3.1&n=2010AU118&oc=500&y0=2020&m0=10&d0=15&h0=0&mi0=0&y1=2020&m1=10&d1=25&h1=0&mi1=0&ti=1.0&tiu=days table now says] 2.6771 au in the Delta column
