The following list is a very small subset of the results of a search for asteroid-deepsky appulses for 2019, presenting only the highlights for the year based on close approaches of brighter asteroids to brighter DSOs. For the complete set visit http://www.minorplanet.info/ObsGuides/Appulses/DSOAppulses.htm
For any event not covered, the Minor Planet Center's web site at https://www.minorplanetcenter.net/cgi-bin/checkmp.cgi allows you to enter the location of a suspected asteroid or supernova and check if there are any known targets in the area.
The table gives the following data:
| Date/Time | Universal Date (MM DD) and Time of closest approach |
| #/Name | The number and name of the asteroid |
| RA/Dec | The J2000 position of the asteroid |
| AM | The approximate visual magnitude of the asteroid |
| Sep/PA | The separation in arcseconds and the position angle from the DSO to the asteroid |
| DSO | The DSO name or catalog designation |
| DM | The approximate total magnitude of the DSO |
| DT | DSO Type: OC = Open Cluster; GC = Globular Cluster; G = Galaxy |
| SE/ME | The elongation in degrees from the sun and moon, respectively |
| MP | The phase of the moon: 0 = New, 1.0 = Full. Positive = waxing; Negative = waning |
| Date | UT | # | Name | RA | Dec | AM | Sep | PA | DSO | DM | DT | SE | ME | MP |
