What is the declination of a planet?
Declination (DEC) is the celestial sphere’s equivalent of latitude and it is expressed in degrees, as is latitude. For DEC, + and – refer to north and south, respectively. The celestial equator is 0° DEC, and the poles are +90° and -90°. Right ascension (RA) is the celestial equivalent of longitude.
What does a declination of 0 mean?
declination, in astronomy, the angular distance of a body north or south of the celestial equator. North declination is considered positive and south, negative. Thus, +90° declination marks the north celestial pole, 0° the celestial equator, and -90° the south celestial pole.
What is the declination of Venus?
RA 20h 1m 45s | Dec -21° 15′ 53″
Venus/Coordinates
Which planet has the highest maximum?
Jupiter may be the largest and most massive planet in the Solar System, but adding more mass to it… [+]
What is Saturn declination?
RA 20h 49m 33s | Dec -18° 35′ 6″
Saturn/Coordinates
Which is the largest and most massive of the planets in our solar system?
Jupiter
Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter’s familiar stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.
What is DEC in astronomy?
R.A. means “right ascension” and Dec. means “declination”; these are the two parts of the equatorial coordinate system. Astronomers developed it to correspond to longitude and latitude on Earth.
What is the solar declination today?
-23° 08′ 13”
The current Right Ascension of The Sun is 17h 21m 06s and the Declination is -23° 08′ 13” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]).
What is Saturn Declination?
What planet has the longest day?
Venus
Venus has the longest rotation period (day) of all the major planets in the Solar System. While the Earth takes 23 hrs 56 mins 04 secs to complete one rotation, Venus takes 243.16 ‘Earth days’ to spin once through 360 degrees.
What is the maximum and minimum declination of a planet?
Maximum Declination — When a planet reaches its highest point north Cross 0 (Zero) — When a planet’s declination is zero and it is crossing from south to north or vice versa Minimum Declination — When a planet reaches its lowest point south
Do all planets transit into the extreme declinations of the Sun?
Not all planets transit into the extreme declinations. The Sun will never appear beyond the maximum declination of 23 degrees 27 minutes. Mercury, Venus and Mars typically transit Out of Bounds once or twice a year.
What is declination in astronomy?
Declination refers to the angular distance of a planet north and south relative to the celestial equator, which is in the same plane as Earth’s equator. Therefore, if you are standing on Earth’s equator, if the planet appears in the north it will have a positive declination, and if it appears in the south it will have a negative declination.
What is the declination of the sun through Pluto?
The ephemeris shows declinations for the Sun through Pluto, including Chiron and excluding the Moon. In the chart, a negative value represents South and a positive value represents North. In other words, if Mercury is shown as +23 degrees and 21 minutes, the declination for that date is 23 N 21.
