The lunar orbit around Earth is elliptical. On average, the distance from Earth to the moon is about 384,400 km. At closest approach (perigee), the moon comes as close as 363,104 km. The farthest away (apogee) it gets is 405,696 km from Earth.
A “supermoon” takes place when a full moon or new moon comes within 90 percent of its closest distance with Earth.
In 2020, three full moon supermoons will occur on March 10 (351198.3 km), April 8 (350564.2 km) and May 7 (353753.9 km). At these instances, the moon will look brighter than ordinary full moons; and about 7% larger than the average-size full moon.
Additionally, three new moon supermoons in 2020 are on September 17 (368459.5 km), October 17 (363392.8 km) and November 15 (364146.4 km).

Here is the challenge – What’s the
youngest moon you can see this year? The infographic will tell you when to hunt
the new moon crescent (hilal),
and where to locate its position in the western sky at sunset from Brunei
Darussalam in 2020.
Note: Prediction method by Mohammad SH. Odeh (New Criterion For Lunar Crescent Visibility, 2005) employed new criterion visibility of the lunar crescent, V. This is only a computational analysis data. The result/declaration of the sighting/beginning of hijrah month should be referenced to official media by the Government.
Bandar Seri Begawan – A penumbral eclipse of the moon will take place on Saturday, January 11, 2020, at pre-dawn hours, from 1.09 a.m. until 5.11 a.m in Brunei Darussalam. The first eclipse of 2020 is also visible from the geographic regions of Europe, Africa, Asia and Australia.
There are three categories of lunar eclipse: total, partial and penumbral. In a penumbral lunar eclipse, only the faint or diffuse outer shadow of Earth (known as penumbra) falls on the moon’s face. This kind of lunar eclipse is much more subtle, and much more difficult to observe, than either a total or partial eclipse of the moon. There is never a dramatic darkening of the moon, as in when the Earth’s darkest shadow (umbra) moves over the Moon during a partial lunar eclipse.

Paris – Sebanyak 110 pasangan nama exoplanet dan bintang induknya diberikan nama melalui kempen IAU100 NameExoWorlds telah diumumkan di sidang media di Paris pada 17 Disember 2019. Bersempena ulang tahun Kesatuan Astronomi Antarabangsa (IAU) yang ke-100 pada tahun ini, kempen di peringkat nasional telah dianjurkan di 110 negara yang melibatkan penyertaan lebih dari 780,000 orang di seluruh dunia, untuk mencadangkan dan memilih nama-nama bagi setiap exoplanet dan bintang induk negara masing-masing.
Projek IAU100 NameExoWorlds telah melihat penyertaan yang meluas dan
besar-besaran di seluruh dunia untuk memberikan masyarakat umum peluang untuk
mencadangkan nama-nama sistem exoplanet yang bermakna, kreatif dan unik bagi
negara masing-masing. Penganjuran ini adalah kali yang kedua dalam sejarah di
mana sebuah kempen telah menghasilkan penamaan bintang dan exoplanet. Pada keseluruhannya,
sebanyak 360,000 cadangan nama telah diterima dari 110 negara. Penganjur program
di setiap negara telah menyenarai pendekkan nama-nama yang dicadangkan, dan
seterusnya dibukakan bagi pemilihan melalui undian kepada orang ramai. Seramai
420,000 orang telah mengundi calon-calon nama yang diberikan. Projek ini akan
memberikan kesan yang berkekalan di mana nama-nama yang dipilih sebagai
pemenang akan digunakan selari dengan tatanama saintifik yang sedia ada dengan
penghargaan kepada individu, kumpulan ataupun institusi yang telah mencadangkan
Paris – More than 110 sets of names of exoplanets and host stars named in the IAU100 NameExoWorlds campaigns were announced at a press conference in Paris (France) on 17 December 2019. Within the framework of the International Astronomical Union’s 100th anniversary commemorations (IAU100) in 2019, more than 110 countries organised national campaigns that stimulated the direct participation of over 780 000 people worldwide, who proposed and selected names for each exoplanet and its host star.
The IAU100 NameExoWorlds project saw massive and widespread participation around the world, as the public eagerly engaged in this exciting opportunity to suggest meaningful, creative and unique names for exoplanet systems for their respective countries. This is only the second time in history that a campaign has led to the naming of stars and exoplanets. Overall, 360 000 proposals for names were received from 110+ countries. The National Committee in each country reduced their proposals to a shortlist of national candidates, which were presented to the public for their votes. A total of 420 000 people voted for their preferred candidates. This project will have a lasting impact, as the winning names will be used in parallel with the existing scientific nomenclature, credited to the person, group or institution that suggested them.
“Astronomical observations over the past generation have now discovered over 4000 planets orbiting other stars — called exoplanets. The number of discoveries continues to double about every 2½ years, revealing remarkable new planet populations and putting our own Earth and Solar System in perspective. Statistically, most of the stars in the sky are likely to be orbited by their own planets — they are everywhere,” said Eric Mamajek, co-chair of the NameExoWorlds Steering Committee. “While astronomers catalogue their new discoveries using telephone-number-like designations, there has been growing interest amongst astronomers and the public alike in also assigning proper names, as is done for Solar System bodies,” Mamajek continued.
A press conference to present the official results of the NameExoWorlds campaign to name more than 100 exoplanets and host stars by the International Astronomical Union (IAU) will be held on Tuesday, 17 December 2019 at 6 pm (Brunei Time) from Observatoire de Paris, Salle Cassini.
Due to the recent outbreak of the 2019 Novel Coronavirus (Covid-19), the Astronomical Society of Brunei Darussalam (PABD) has postponed all our activities such as annual meeting, stargazing, new moon observation etc. until further notice and focus on implementing Astronomy at Home. This is in view of prevention and to control the spread of the infection in Brunei Darussalam.
