* Wrapping the asteroid in a sheet of reflective plastic such as [[metallized polyethylene terephthalate|aluminized PET film]] as a [[solar sail]]
* "Painting" or dusting the object with [[titanium dioxide]] (white) to alter its trajectory via increased reflected radiation pressure or with [[soot]] (black) to alter its trajectory via the [[Yarkovsky effect]].
* [[planetary science|Planetary scientist]] [[Eugene Shoemaker]] in 1996 proposed<ref>--in a lecture to the [[Arizona Geological Society]] in 12–96.</ref> deflecting a potential impactor by releasing a cloud of steam in the path of the object, hopefully gently slowing it.

* [[Explosively pumped flux compression generator|Magnetic flux compression]] to magnetically brake and or capture objects that contain a high percentage of [[meteoric iron]] by deploying a wide coil of wire in its orbital path and when it passes through, [[Inductance]] creates an [[electromagnet]] solenoid to be generated.<ref>{{cite web |url=http://www.obtronics.net/htc/technogy/elec/elmag_04.htm |title=How to Colonize an Asteroid Solenoids |url-status=dead |archive-url=https://web.archive.org/web/20060103083009/http://www.obtronics.net/htc/technogy/elec/elmag_04.htm |archive-date=2006-01-03 }}</ref><ref>{{cite web |url=http://www.nss.org/adastra/volume18/durda.html |title=National Space Society, From Ad Astra, Volume 18 Number 2, Summer 2006 |access-date=2013-11-25 |archive-url=https://web.archive.org/web/20170721141759/http://www.nss.org/adastra/volume18/durda.html |archive-date=2017-07-21 |url-status=dead }}</ref>
