📋 About This Mod

A configurable astronomy mod that adds a realistic night sky with real life stars, planets and much more. This mod is for those who want to explore the stars while playing minecraft.

## Features - Real life constellations and stars - Moving planets with moons - Realistic sun and moon positions, longer days or nights throughout the seasons - Shooting Stars with annual Meteor Showers - Nebulae, Galaxies, and the Milky Way - Rare astronomical events, such as solar and lunar eclipses - "Live mode" to show the current irl sky in-game. - Makes the spyglass useful - Full customizability, with custom planets or stars.

_If you are only interested in simply replacing the stars and none of the mod's other features, check out (https://modrinth.com/mod/astrocraft-lite) (Fabric and Neoforge)._

### Stars Astrocraft replaces Minecraft's default stars with stars from real life. Stars retain their vanilla-style, but with variation in hues, some being more reddish, others blue. You can find any constellation in-game. Through the night, all these stars revolve around the north star (Polaris):

Some stars are variable, meaning they vary in brightness over time.

### Galaxies, Nebulae, Clusters The milky way is faintly visible at night, along with numerous other objects. These include massive galaxies like Andromeda and Triangulum, or smaller planetary nebulae like the Ring Nebula. The Milky Way and other deep-sky objects become brighter and more visible from high mountain peaks, but are easily outshone when the moon is out.

### Shooting Stars / Meteor Showers At night, you can occasionally see streaks of light shoot across the sky. Meteors often belong to a meteor shower, where multiple will appear to radiate from the same point in the sky. Some are sporadic, not associated with any shower. Meteors showers occur at predictable times each year. The Perseids for example, are visible around the middle of summer, around MC day 142. Occasionally, certain meteor showers can even produce "meteor storms". Below are a few example meteor showers: |Name |Radiant |Peak Day (/365¼)|Peak Day (/96)| |-------------|-------------------|----------------|--------------| |Lyrids |Lyra |33 |9 | |Eta Aquariids|Aquarius |46 |12 | |Perseids |Cassiopeia, Perseus|142 |37 | |Orionids |Orion |211 |55 | |Leonids |Leo |239 |63 | |Geminids |Gemini |266 |70 | |Quadrantids |Boötes |287 |75 |

### Spyglass The spyglass is an essential tool for exploring Astrocraft's skies, as it lets you observe an area of the sky in much greater detail. It increases the brightness of stars, and shows objects that would otherwise be too dim, like Uranus or Neptune.

What you can see using a spyglass depends on multiple factors, such as Y position or moon phase. It is better to climb a mountain and point upwards to observe very dim objects like nebulae.

Using the mouse scroll wheel, you can zoom in and out up to 500x.

Planets / Solar System Objects By default, this mod adds all major planets, along with many other objects in the solar system. Planets are rendered similar to stars when not zoomed in, although typically brighter, larger and more vividly colored. Unlike stars, planets move against the fixed background of stars, traversing the zodiac as the days go by.

The positions of these planets in the sky are calculated using their orbital parameters (fully configurable), while also taking into account earth's own orbit. These include: - Semi-Major Axis - Orbital period - Eccentricity - Inclination - Precession

The brightness or size of a planet is calculated using: - Diameter and Albedo - Distance to Earth / Observing Planet - Distance to the Sun - Phase Angle (Different phase curve models are used for different planets)

Satellites of planets (including The Moon) or even the Sun use the same algorithm. When the angular
