Uranus¶

Class to model Uranus planet.

Uranus examples

Uranus - VSOP87-Parameters

class pyplanets.planets.uranus.Uranus(epoch)[source]¶

Class Uranus models that planet.

__init__(epoch)[source]¶

Initializes an object of type planet for a given date (epoch) with: its orbital parameters (ephemeredes) given by VSOP87.

Parameters: epoch (Epoch) – Epoch to which all computations of this instance refer, as an Epoch object
Raises: TypeError if epoch is of wrong type.

aphelion() → pyplanets.core.epoch.Epoch [source]¶

This method computes the time of Aphelion closer to a given epoch.

Returns: The epoch of the desired Perihelion (or Aphelion)
Return type: Epoch

Note

The solution provided by this method may have several days of error.

>>> epoch = Epoch(2090, 1, 1.0)
>>> e = Uranus(epoch).aphelion()
>>> y, m, d = e.get_date()
>>> print(y)
2092
>>> print(m)
11
>>> print(int(d))
22

conjunction() → pyplanets.core.epoch.Epoch [source]¶

This method computes the time of the conjunction closest to the given epoch.

Returns: The time when the conjunction happens, as an Epoch
Return type: Epoch
Raises: ValueError if input epoch outside the -2000/4000 range.

>>> epoch = Epoch(1993, 10, 1.0)
>>> conj = Uranus(epoch).conjunction()
>>> y, m, d = conj.get_date()
>>> print(y)
1994
>>> print(m)
1
>>> print(round(d, 4))
12.7365

static magnitude(sun_dist, earth_dist)[source]¶

This function computes the approximate magnitude of Uranus.

Parameters

sun_dist (float) – Distance from Uranus to Sun, in Astronomical Units
earth_dist (float) – Distance from Uranus to Earth, in Astronomical Units

Returns

Uranus’s magnitude

Return type

float

opposition() → pyplanets.core.epoch.Epoch [source]¶

This method computes the time of the opposition closest to the given epoch.

Returns: The time when the opposition happens, as an Epoch
Return type: Epoch
Raises: ValueError if input epoch outside the -2000/4000 range.

>>> epoch = Epoch(1780, 12, 1.0)
>>> oppo = Uranus(epoch).opposition()
>>> y, m, d = oppo.get_date()
>>> print(y)
1780
>>> print(m)
12
>>> print(round(d, 4))
17.5998

perihelion() → pyplanets.core.epoch.Epoch [source]¶

This method computes the time of Perihelion closer to a given epoch.

Returns: The epoch of the desired Perihelion (or Aphelion)
Return type: Epoch

Note

The solution provided by this method may have several days of error.

>>> epoch = Epoch(1880, 1, 1.0)
>>> e = Uranus(epoch).perihelion()
>>> y, m, d = e.get_date()
>>> print(y)
1882
>>> print(m)
3
>>> print(int(d))
18
