Asteroid Ephemeris, 1900 to 2050: Including Chiron and the Black Moon Lilith

Product Information

Note that the four major asteroids, included in the monthly ephemerides above for the year 2025, are Ceres, Juno, Vesta, and Pallas. Also added are Eros, Sappho, Psyche, and Chiron. This was a custom ephemeris built using the excellent and highly recommended software program, Sirius 3.0. The Planets & Asteroids Ephemeris includes the major planets, North Node, Chiron, Lilith, and the four major asteroids in one table. This particular ephemeris is good for those who are not yet familiar with the planets’ symbols or glyphs–or simply prefer the written word–as it uses abbreviations for the planets, asteroids, and signs. Asteroids are small Solar System objects that originate from times preceding planet formation. Typically, when rotating about its principal axis of inertia, an asteroid exhibits a periodic change of brightness caused by the varying part of its surface being both illuminated by the Sun and visible to the observer. On one hand, a photometric lightcurve is the result of photometric observations extending over a time span covering a substantial part of the rotation period or more. On the other hand, a photometric phase curve is the result of observations of the change in an asteroid’s apparent brightness obtained at different epochs during a single apparition, corresponding to a slowly changing Sun-observer-object geometry. What’s an astrological ephemeris? It’s a collection of tables that list planetary movement. Astrologers use an ephemeris to view the positions of planets, asteroids, and other cosmic bodies at any given time: past, present, and future. The reviewer AC declared a past collaboration with the author AC to the handling editor. Publisher’s Note

Pallas in our natal charts represents strategy, wisdom, planning, intuition, intelligence, strength, skill, insight, upheaval, activism, and politics. This is a point where illusions are stripped away, connections are made, and strategies are created. Pallas is an agent of change and seeks to raise awareness. You can compare your Eros sign with your partner’s Psyche sign, and then do the reverse — compare your Psyche sign with your partner’s Eros sign — to get a good idea how you two combine on a romantic and sexual level. Use our Love Sign Compatibility Grid to find out. Eros in Astrology: Signs for 1940-2010 1940A bit slow; helps in identifying asteroids that may be important for a particular chart, which you can then specify as Additional Objects. Probably best combined with the Sort by Degrees of Zodiac option. This is useful too. The ephemerides above show the daily positions, month to month in the year 2021, of the four major asteroids, Chiron, and the minor asteroids Eros, Psyche, and Sappho. lightcurves like lightcurve k ̃, balancing the weights of lightcurves with drastically different numbers of observations. We recall that the systematic errors include, in addition to the observational errors, the effects of simplified forward modeling, in particular, for the phase function in Eqs 8– 10.

We extend the work by Martikainen et al. (2021) by providing computational tools for the derivation of asteroid phase functions using fictitious spherical asteroids with equal surface properties. In earlier works, we have described these phase functions as being proper phase functions that describe the intrinsic properties of the surfaces. We apply the methods to the asteroids studied by Martikainen et al. (2021), by starting from their results of Markov-chain Monte Carlo (MCMC) lightcurve inversion for some 500 asteroids. Furthermore, we generalize the studies by Martikainen et al. (2021) and Muinonen et al. (2020) by incorporating a combined linear-exponential model of phase functions on the magnitude scale. Lightcurve inversion for the GS-asteroid data was carried out using Lommel-Seeliger ellipsoids and general convex shapes for two principal cases: one where all of the lightcurves were assumed to represent relative photometry and the other where all were assumed to represent absolute photometry. In addition, two error models were studied for each of the principal cases: the first model assigned a unit weight for each ground-based lightcurve, whereas the second model differed for the relative and absolute photometry as described in Section 3. Consequently, the analysis consisted of 8 different case studies. The ephemerides above display each planet, asteroid, or point by degree and sign (longitude) at Midnight in the Eastern time zone at a daily rate. With an ephemeris, we can follow their daily progress/movement and get a good understanding of sign change dates.

Selected by the user. It can be a major-body or small-body. Center (or coordinate origin, or observering location) is requested, “n.a.” symbols will appear in output (meaning “not available”). 2. Osculating orbital elements table Where Sappho is, there is greater vulnerability, yearning, desire for poetry and transcendence, and love. b) you compute the position for one moment with the speed flag set. Then you look at the speed in longitude value, whether it is positive or negative. This value is found in xx[3].
