2026 ED138: Why Astronomers Call It a Dwarf Planet Candidate
Learn what makes 2026 ED138 a dwarf planet candidate, how the IAU defines dwarf planets, and which measurements could confirm its status.
To find today's moonrise time in Australia, choose your city and local date on a moonrise calendar—not just “Australia” in a search box. Moonrise can differ substantially between Sydney, Brisbane, Adelaide, Perth, and smaller towns. For a fast answer, use a city-specific moonrise table; for an independent calculation, use the U.S. Naval Observatory. If you actually want to see or photograph the Moon, check cloud forecasts and your eastern horizon as well.
City-specific starting points: Sydney, Melbourne, Brisbane, Adelaide, Perth, Darwin, Hobart, Canberra. These pages provide moonrise and moonset calendars and additional information such as lunar phase and direction. Pick the nearest location, not whichever city appears first in search results.
| Option | Best for | What to watch for |
|---|---|---|
| Timeanddate city moon calendar | Fast daily checks, local clock times, monthly overview, rising direction | Confirm the city and selected date; the page can show a “next moonrise” that belongs to tomorrow. |
| U.S. Naval Observatory calculator | Independent astronomical rise/set calculation for a chosen date and coordinates | You must enter an Australian location's coordinates and correct time-zone offset; its automatic U.S. daylight saving setting is not an Australian DST calculator. |
| Bureau of Meteorology forecast | Deciding whether the Moon is likely to be visible outdoors | Cloud forecasts complement moonrise times; they do not replace an astronomical moonrise calculation. |
The U.S. Naval Observatory's Complete Sun and Moon Data for One Day computes Moonrise, Moonset, and transit for a specified date and geographical coordinates. It is especially useful if you are outside a major city or want to double-check a listed time. For an Australian location, use the latitude and longitude option rather than the U.S.-only city finder. Enter the applicable offset east of UTC, and do not select the option for U.S. daylight saving rules. The service does not determine Australian DST automatically for manually supplied coordinates.
The observatory also publishes definitions and calculation limitations. A published moonrise is a computed horizon crossing under standard assumptions, not a guarantee that you will see the Moon at that exact minute from a valley, behind a building, or through clouds.
On October 29, 2026, daylight saving time is in effect in New South Wales, Victoria, the Australian Capital Territory, Tasmania, and South Australia. Queensland, Western Australia, and the Northern Territory stay on standard time. Australia's Reserve Bank daylight saving schedule confirms that the 2026 change began on October 4, while Tourism Australia's time-zone guide explains the regional offsets.
| City or region | Local zone on October 29, 2026 | UTC offset |
|---|---|---|
| Sydney, Melbourne, Canberra, Hobart | AEDT — Australian Eastern Daylight Time | UTC+11:00 |
| Adelaide | ACDT — Australian Central Daylight Time | UTC+10:30 |
| Brisbane | AEST — Australian Eastern Standard Time | UTC+10:00 |
| Darwin | ACST — Australian Central Standard Time | UTC+09:30 |
| Perth | AWST — Australian Western Standard Time | UTC+08:00 |
These offsets apply to the stated date, not every date of the year. Sydney and Melbourne use AEST (UTC+10:00) outside daylight saving; Adelaide switches to ACST (UTC+09:30). Border locations such as Broken Hill, and places with special time-zone arrangements, require checking the exact locality. If a moonrise source displays UTC instead of local time, convert using the offset for the date of moonrise, and verify whether the conversion crosses midnight into another calendar day.
A blank or dash does not automatically mean the website is broken. The Moon rises on a schedule that shifts from one day to the next, and an individual calendar date may contain no moonrise event at a given location. Check the previous and following date before assuming a value is missing. Moonrise may also occur during daylight, so it is not necessarily a nighttime event.
Two reputable calculators can differ slightly because of rounding and their modeling assumptions. For actual visibility, the horizon matters: hills and tall buildings can delay the first unobstructed view beyond the published calculation. The Moon's phase affects how easy it is to see, but a full Moon does not mean every moonrise happens at an identical clock time across Australia.
If your goal is a view rather than a number, start with the calculated moonrise and add three checks:
For a coastal photograph, note that a low Moon can be hard to pick out against bright twilight. For a backyard look, the Moon may become more obvious after it climbs above roofs or trees. These are practical differences between computed moonrise and first visible moon.
The practical choice: Use a city-specific Timeanddate calendar for a quick answer, the U.S. Naval Observatory when you need a coordinate-based calculation, and the Bureau of Meteorology when deciding whether to head outside. Recheck the date and time zone each time; yesterday's moonrise time is not a reliable substitute for today's.
