# For what period of time can planets be viewed from the North Pole as just being there?

I would like details on observations (since North Pole is not possible, approximately around the North Pole) which tell us for how long are planets visible from the North Pole?

I understand that during the 6 months of daylight, the sunlight would obscure the sight of other planets. Despite that for what time period (years, months or days) are planets visible from the North Pole?

And how is this time period justified?

Hypothetical example: observations show that Jupiter is visible from the North Pole for 1 month in a year. I don’t want the answer to be based on common logic calculating the period and saying that the observation should be this. Rather, the period as per actual observations, and then if necessary, justified by calculations.

• It isn't like a lot of people have spent time at the North Pole doing observations. Commented Oct 17, 2023 at 20:47
• Anything with a declination (of date) greater than or equal to 0 will be visible from the North pole. You can use JPL Horizons to compute the times each is visible: ssd.jpl.nasa.gov/horizons/app.html# Commented Oct 18, 2023 at 3:16
• As far as I can tell the northernmost observatory is the Greenland Telescope at Thule en.wikipedia.org/wiki/Greenland_Telescope at 76 degrees north (but it is a radio telescope). There are apparently plans for a telescope in Eureka, Nunavut, 80 degrees north. Generally astronomical observations at the north pole are rather ad hoc. However, the South Pole Telescope (SPT) is located at the Amundsen-Scott South Pole Station, Antarctica and more or less exactly at the south pole. Commented Oct 18, 2023 at 8:25
