Merry Christmas! I am a novice astrophotographer and just joined Astrobin. I have been tracing a possible Kuiper belt object since Nov. 20. I initially thought it was in the outer solar system, but angular diameter observations show it was between Venus’ orbit and Mercury’s orbit for Thanksgiving. Current angular diameter is on par with a distant Mars. It is definitely not a comet as it sometimes produces a temporary coma. I had planned to map this object before my announcement, but the weather has cancelled that plan. The bad weather did have one benefit. I learned enough of the MPC format to let you have your turn at it.

I don’t have a MPC code, so use the closest736. All observations and GPS are available upon request. Target is very dark so wait ten minutes after sundown before seeing it. It is red in my finderscope. It was too windy for barlows, but I made do with 299ms and 9.721 db gain. Do you have any advice for imaging Kuiper belt objects this close? As a New Year’s gift I am throwing this possible Earth impacter in. Enjoy! 2016 11 25.01747 18 25 58.50 -27 19 22.009.0 XXX 2016 11 22.03064 18 13 36.10 -24 23 15.00 9.0XXX 2016 11 24.04514 18 26 00.00 -24 03 10.00 9.0XXX |

Cloudy here but wish I could confirm your observations! Hopefully someone else can. |

Same here but sounds like an interesting hunt awaits. Weather aside would have no idea how to find myself but hopefully some expertise is here that can help. |

Very interesting! Can you explain the MPC format or provide a link? Thanks! |

The MPC Format refers to the minor planet center’s format. You can use the information I have provided to calculate the orbit. My early attempts ended with failure, so I am waiting for more information before I make another attempt. All I ask to go to the last set of coordinates I have provided and scroll down to the horizon. See for yourself if I am lying. |

David, 20h 24m 33.8517s, -21° 49' 02.092" are coordinate of comet 45P/Honda-Mrkos-Pajdusakova with magnitude 8.71. This is the more closest detectably object today in region. |

Here is the latest coordinate. 2016 12 20.04676 20 40 57.00 -23 29 36.00 I thank you for the comet 45P/Honda-Mrkos-Pajdusakovasuggestion. Comets don’t have moons, andthis one has several. That is how I knowit is not a comet. Would you like themoons’ coordinates so you could calculate their orbits? |

How about a new image? If you can detect several moons, there should be a star background visible as well. Not so much time left : according to your data, the object is coming back in RA. Good luck ! Wanni P.S. Constant bad weather at my place since weeks. Otherwise I would try it myself, although I am highly sceptical about your find. I wonder why nobody else could verfiy your observation, nothing heard from professional observatories yet. Did you try to contact them? |

After thinking about it, the target might be producing a coma. When it does it you see what looks like a line of comets in your telescope. Since the moons are somewhat spaced out now you would have to move it around. So if you are interested in seeing comets, try looking at this object tonight. |

Wanni: Kuiper belt objects with several moons and apparently as large as Mars..... Highly unlikely. Google or check wiki to see what the largest few Kuipter belt objects are like. Even Pluto does not come close to this description. |

Wei-Hao Wang:Wanni:Kuiper belt objects with several moons and apparently as large as Mars..... Highly unlikely. Google or check wiki to see what the largest few Kuipter belt objects are like. Even Pluto does not come close to this description. I know, I imaged Pluto several times, which was quite a challenge. Only by overlaying two images a day apart, I could verfiy Pluto by it's movement relativ to the background stars. (see at my page) But obviously David is tracking something. I took all his data and made a plot over RA/DE. The path looks consistant, but what it is, we don't know. So either he is seeing really something or it is a complete hoax. 8) Wanni |

2016 12 21.04755 20 47 09.00 -25 25 33.00 Thanks Wanni. You don’t know what this means for me. I shot the target with my deep sky camera. There has been a reason I have not been honest with you about what I am seeing. I now submit evidence showing the target is more the size of Earth than Mars. To do this you need to download my image and blow it up to 400%. Clearly the tails are ionized or they would be pointing directly behind the sun. You will see a bow shock. |

I computed its trajectory and looks like it's headed straight towards Earth! |

The weather hasn't been helpful with taking photos. I am likely out till the New Year. If you do seek this object out my only advice is expect the unexpected. It is quite a variable magnitude object. I have seen it as a comet like object so bright I thought it would be visible to the naked eye to so dim I was surprised it showed up in my finding scope. It will show up as a red object or as a bright comet like object your finder scope. If you do seek this object, please reply so I see if I lived up to your expectations. |

Good news. My cloudy nights have been far from in vain. I was unable to use my location to calculate the orbit. I had to use Houston as the location. There are multiple orbits that fit my data soI won’t publish the details, with one exception. The target will be make its’ closest approach in May. I can’t see all the uncertainties putting the target out your finder scope’s range by then, so I will publish the geocentric coordinates so you can see it. The target will be either a bright star or a more likely red object in your finderscope. #Geocentric Date (UTC) RA Dec delta r elong ---- -- -- ------------ ------------ ------ ------ ----- 2016 12 28 22 5731.662 -09 14 46.35 .92203 1.0340 65.6 2016 12 29 23 0037.793 -08 49 09.72 .92192 1.0319 65.5 2016 12 30 23 0344.091 -08 23 23.75 .92177 1.0297 65.3 2016 12 31 23 0650.570 -07 57 28.64 .92156 1.0276 65.2 2017 01 01 23 0957.245 -07 31 24.62 .92131 1.0255 65.1 2017 01 02 23 1304.130 -07 05 11.90 .92100 1.0234 64.9 2017 01 03 23 1611.237 -06 38 50.73 .92065 1.0213 64.8 2017 01 04 23 1918.581 -06 12 21.33 .92025 1.0192 64.6 2017 01 05 23 2226.175 -05 45 43.94 .91980 1.0172 64.5 2017 01 06 23 2534.032 -05 18 58.83 .91930 1.0151 64.4 2017 01 07 23 2842.168 -04 52 06.24 .91876 1.0131 64.3 2017 01 08 23 3150.595 -04 25 06.43 .91816 1.0111 64.1 2017 01 09 23 3459.330 -03 57 59.66 .91753 1.0091 64.0 2017 01 10 23 3808.390 -03 30 46.20 .91684 1.0071 63.9 2017 01 11 23 4117.794 -03 03 26.30 .91612 1.0052 63.8 2017 01 12 23 4427.562 -02 36 00.24 .91534 1.0033 63.7 2017 01 13 23 4737.717 -02 08 28.26 .91453 1.0013 63.6 2017 01 14 23 5048.284 -01 40 50.62 .91368 0.9995 63.5 2017 01 15 23 5359.287 -01 13 07.60 .91278 0.9976 63.3 2017 01 16 23 5710.753 -00 45 19.44 .91184 0.9957 63.2 2017 01 17 00 0022.710 -00 17 26.43 .91086 0.9939 63.1 2017 01 18 00 0335.184 +00 10 31.17 .90985 0.9921 63.0 2017 01 19 00 0648.202 +00 38 33.08 .90879 0.9904 63.0 2017 01 20 00 1001.793 +01 06 39.00 .90770 .98862 62.9 2017 01 21 00 1315.983 +01 34 48.65 .90657 .98691 62.8 2017 01 22 00 1630.800 +02 03 01.70 .90541 .98522 62.7 2017 01 23 00 1946.271 +02 31 17.86 .90420 .98355 62.6 2017 01 24 00 2302.423 +02 59 36.79 .90296 .98192 62.5 2017 01 25 00 2619.284 +03 27 58.17 .90169 .98032 62.4 2017 01 26 00 2936.880 +03 56 21.66 .90038 .97874 62.4 2017 01 27 00 3255.238 +04 24 46.91 .89904 .97720 62.3 2017 01 28 00 3614.385 +04 53 13.56 .89766 .97568 62.2 2017 01 29 00 3934.347 +05 21 41.24 .89625 .97420 62.2 2017 01 30 00 4255.148 +05 50 09.56 .89480 .97275 62.1 2017 01 31 00 4616.815 +06 18 38.13 .89332 .97133 62.0 |
