The new comet C/2020 F3 was first spotted by NASA's NEOWISE satellite in March 2020. It is now visible in the NE sky just before dawn. The C may refer to it's non-periodic nature (so far). What doe...
I have read in several places that the orbital period of comet Neowise c2020 F3 is about 6800 years. In several popular media sources it is said that we will be able to see the same comet after ~6800
I have read in Wikipedia about Comet C/2020 F3 Neowise that it's orbit is near-parabolic. But in another section, it says that it is a non-periodic comet whlith orbital period ranging from 4500 ye...
Over the next few days, NEOWISE will move higher in the sky and be easier to spot, reaching its apex on July 23, when it makes its closest approach to Earth. It says that I'll be able to see the comet "under the Big Dipper about 10 degrees above the horizon". What "horizon" is the article referring to?
NEOWISE is the brightest comet since comet McNaught, but McNaught, with a peak mangitude of -5.5, was about 500 times brighter. (based on the estimate that Neowise is about as bright as the 20th brightest star, roughly 1.25 magnitude).
So, I have been trying to figure out the bolometric luminosity of the comet C/2020 F3 (Neowise) on the 22nd of June, 2020. At that time, Neowise was $1.4$ AU away from Earth and had an apparent mag...
I'd like to get .altaz(next_several_weeks) of this comet from Skyfield and .separation_from() other planets. It reads the JPL development ephemerides and can import star catalogs, but is there a way to add some orbital elements for a given comet or asteroid from some standard database and at least approximately propagate them to get an ...
2 I live in Los Angeles and have a camera adapter for my telescope -- nothing fancy just an Astromaster 114. What is the optimal time, in terms of dark sky and bright comet, to take a photo of Comet NEOWISE? I.e., when will it be brightest relative to the surround sky? When will it be largest? And, lastly, what is the best time tonight to view it?
In comparison, the comet NEOWISE has a nucleus diameter of 5 km. I am guessing this means it is too small to have a debris trail that produces periodic meteor showers? I was not able to find data about the length of these comets' tails. The Question What determines if the debris from a comet will produce periodic meteor showers in the sky?
I have had an impossible time trying to locate this comet. My lat/long is 38.3/-82.4. My elevation is 705ft. The application that I'm using shows me exactly where Neowise is supposed to be (North E...
