Ten 2023 ET2 dopiero się dziś pojawił! Dzięki! Chyba powracamy do regularnych odkryć! {...}

do 25 marca 2022 mieliśmy 43 przeloty.
Mieliśmy teraz 24 dni przerwy w przelotach. Na początku roku były 2 okresy przerw w przelotach wynoszących 16 dni. W czerwcu 2022 było 20 dni przerwy.

Extremely close approach of asteroid 2023 RS at just 0.03 LD – the 5th closest on record
Thursday, September 7, 2023

A newly-discovered asteroid designated 2023 RS flew past our planet at an extremely close distance of just 0.027 LD or 0.00007 AU (~10 361 km / 6 438 miles) from the center of Earth at 14:26 UTC on September 7, 2023. This is the 53rd known asteroid to fly past Earth within 1 lunar distance since the start of the year and the first so far this month.

The asteroid’s nearest point was around 2 381 km (1 479 miles) from the surface, ranking 2023 RS as the fifth closest asteroid flyby ever recorded.

The year 2023 also witnessed the fourth closest encounter with asteroid 2023 BU at 0.00007 AU on January 27. The third closest was in 2021 with 2021 UA1 at 0.00007 AU, followed by the second closest in 2020 with 2020 QG at 0.00006 AU. The closest known flyby occurred at 17:21 UTC on November 13, 2020, with asteroid 2020 VT4 approaching within 0.00005 AU (0.018 LD/6 746 km/4 191 miles) of Earth’s center.

2023 RS (temporary ID C9FMVU2) was first observed at Mt. Lemmon Survey just a couple of hours before its close approach. The object belongs to the Apollo group of asteroids and has an estimated diameter between 0.93 and 2.1 m (3 – 6.9 feet). It flew past us at a speed of 13.6 km/s.

Its next close approach will take place on January 29, 2024, at a distance of about 0.45 AU.

If asteroids measuring 0.93 m (3 feet) and 2.1 m (6.9 feet) in width were to enter Earth’s atmosphere, they would largely burn up due to intense friction with the air, creating bright streaks in the sky. The 0.93-m asteroid, being smaller, would likely disintegrate entirely before reaching the Earth’s surface. The 2.1-m asteroid, while also small, might have fragments that survive the atmospheric burn-up and reach the surface as meteorites. However, the impact of such fragments would be localized and unlikely to cause significant damage or harm. The primary effects of these asteroids would be the spectacular visual displays they’d offer, particularly during nighttime entries.

Asteroid 2023 SL5 flew past Earth at 0.1 LD
Monday, September 25, 2023

A newly-discovered asteroid designated 2023 SL5 flew past Earth at a distance of 0.13 LD / 0.00035 AU (51 864 km / 32 227 miles) from the center of our planet at 07:54 UTC on September 20, 2023. This is the 65th known asteroid to fly past Earth since the start of the year and the 12th so far this month.

2023 SL5 was first observed at Catalina Sky Survey, Arizona on September 21 — one day after it made the close approach.

The object belongs to the Aten – a relatively rare – group of asteroids. Named after asteroid 2062 Aten, the first of its kind, Aten asteroids have semi-major axes smaller than Earth’s but are still greater than one Astronomical Unit (AU). This means that they orbit the Sun within a radius closer to the Earth’s own orbit, but may still cross Earth’s orbital path at certain points, making them significant from both a scientific and hazard-assessment perspective.

Its estimated diameter is between 4.6 and 10 m (15 – 33 feet).

Bliskie przeloty obiektów NEO w 2023 roku
Nieustannie przypominamy o naszej liście bliskich przelotów małych i większych kamyczków nieopodal Ziemi w 2023 roku.
https://kosmonauta.net/2023/10/planetoidy-neo-w-2023-roku/
Choć odkryć jest mniej niż rok czy dwa lata temu, od września notuje się więcej detekcji. Czyżby astronomowie zabrali się do pracy po wakacjach?

Wśród odkryć jest meteoroid 2023 CX1,
https://kosmonauta.net/2023/02/trzy-meteoryty-w-trzy-dni/
który został odkryty jeszcze przed wejściem w atmosferę Ziemi. Udało się znaleźć meteoryty po spadku!

We wrześniu wyraźny wzrost -14 przelotów bliskich, czyli dokładnie 2 razy więcej niż we wrześniu 2022.

Asteroid 2023 UR10 flew past Earth at just 0.036 LD — 9th closest on record
Tuesday, October 31, 2023

A newly-discovered asteroid designated 2023 UR10 flew past Earth at just 0.036 LD / 0.00009 AU (13 951 km / 8 669 miles) from the center of our planet at 04:27 UTC on October 20, 2023. This is about 7 580 km (4 709 miles) from the surface.

2023 UR10 was first observed at Pan-STARRS 1, Haleakala, Hawaii on October 21 — one day after it made its close approach to our planet.

Its estimated diameter is between 2.7 and 6 m (8.8 – 19.7 feet)

Since the beginning of the year, our space observatories have identified a total of 86 asteroids whose orbits come within 1 lunar distance from Earth’s center.

2023 UR10 is the 9th closest known asteroid flyby on record (since 1900) and the third asteroid discovered in 2023 to enter the list of the top 10 closest flybys on record.

The closest known flyby was that of the asteroid 2020 VT4, which came within 0.00005 AU from the center of Earth on November 13, 2020. The asteroid had a relative velocity of 13.43 km/s and a diameter estimated between 5 and 11 m (16.4 – 36 feet). Another example is 2021 UA1, which ranks as the 2nd closest flyby, coming within 0.00006 AU on October 25, 2021, with a relative velocity of 15.84 km/s and a diameter between 1.1 and 2.5 m (3.6 – 8.2 feet).

Alongside 2023 UR10, which is the 9th closest flyby, there are two other asteroids making the list in the same year — 2023 RS and 2023 BU.

2023 RS flew past us on September 7, 2023, at 14:26 UTC, with a nominal distance of 0.00007 AU and a relative velocity of 13.59 km/s. Its estimated diameter ranges from 0.91 to 2 m (2.9 – 6.6 feet), making it one of the smaller asteroids on the list. It ranks 4th in terms of closeness to Earth.

2023 BU flew past us on January 27 at 00:29 UTC. It had a nominal distance of ~0.00007 AU and a much slower relative velocity of 9.27 km/s. Its estimated diameter ranges between 3.1 and 6.9 m (10.2 – 22.6 feet). It ranks 5th on the list of closest flybys.

Zobaczymy, które źródło okaże się bliższe prawdy.
Byłoby ciekawie, gdyby okazało się, że to będzie bliski przelot.

Na kosmonaucie pojawiają się czasem inne wielkości asteroid niż w powyższym źródle.
Do tej pory w liście forumowej z reguły przyjmowałem w tym względzie wersję z Kosmonauty, ale od 2024 zamierzam podawać dane wg powyższego źródła , przytaczajac jednocześnie wersję z Kosmonauty w przypadku rozbieżności.

Asteroid 2024 BX1 (Sar2736) impacts Earth’s atmosphere over Berlin, Germany – the 8th predicted impact on record
Sunday, January 21, 2024

A small asteroid designated 2024 BX1 (temporary designation Sar2736) impacted Earth’s atmosphere near Berlin, Germany at 00:33 UTC on January 21, 2024. This asteroid was discovered about 3 hours before impact, making it the 8th asteroid to be discovered before impacting Earth.

The object belonged to the Apollo class of Asteroids and had an estimated diameter between 0.7 and 1.6 m (2.23 – 5.2 feet).

2024 BX1 was discovered about 150 minutes before impact by astronomer Krisztián Sárneczky at GINOP-KHK, Piszkesteto Station in Hungary.

This is the third discovery of Earth’s impactor made by Sárneczky. His previous discoveries were 2022 EB2 which impacted Earth’s atmosphere southwest of Jan Mayen island in the Arctic Ocean on March 21, 2022, and 2023 CX1 which impacted over the English Channel, between England and France on February 13, 2023.

Asteroid 2024 BX1 disintegrated just west of Berlin but it’s likely some pieces of it survived the entry.
