Neptune and Triton Series, Part 1
When we look up at the night sky, Jupiter and Saturn still feel, in some sense, close. They are distant worlds, obviously, but they remain part of ordinary skywatching. You can point them out. You can notice them with the naked eye. They feel like members of the visible Solar System.
Neptune Full-Disk Portrait
Produced from images taken by NASA’s Voyager 2 in the summer of 1989. Neptune does not.
Neptune sits far beyond that familiar zone. It is the eighth planet from the Sun, more than 30 astronomical units away on average. An astronomical unit, or AU, is the average distance between Earth and the Sun, about 150 million kilometres. On that scale, Earth is at 1 AU, Jupiter is about 5.2 AU, Saturn about 9.5 AU, and Neptune a little over 30 AU from the Sun. Neptune is therefore roughly three times farther from the Sun than Saturn and nearly six times farther out than Jupiter. It is also so distant and faint that it is not visible to the naked eye.
The Neptune System by NASA's James Webb Space Telescope
Captured by NIRCam, this image displays Neptune's turbulent atmosphere, rings, and the prominent moon Triton (top left). That scale matters.
It is easy to memorize the order of the planets and still not really feel the geometry of the Solar System. Neptune helps correct that. If Earth were one metre from the Sun in a scale model, Jupiter would be about 5.2 metres away, Saturn about 9.5 metres away, and Neptune around 30 metres away. The outer Solar System is not just a little farther out. It is vastly farther out.
That distance also changes the character of sunlight itself. By the time sunlight reaches Neptune, it is far weaker than what we experience on Earth. Neptune is cold, dark, and remote, yet somehow still dynamic. NASA describes it as an ice giant whipped by supersonic winds, with methane in its atmosphere contributing to its famous blue colour. Methane absorbs red wavelengths of light, which is one reason Neptune appears blue in visible light.
And that, for me, is part of Neptune’s fascination. It would already be interesting if it were only distant. But it is not only distant. It is active, structured, meteorologically violent, and scientifically unfinished.
3D Visualization of Voyager 2 by NASA
We have only visited it once.
NASA’s Voyager 2 spacecraft flew past Neptune on August 25, 1989, and remains the only spacecraft ever to visit Neptune. That single flyby transformed Neptune from a remote blue point into a real planetary system with storms, rings, and a moon that turned out to be one of the strangest worlds in the Solar System.
There is something humbling about that. We speak of Neptune as if it were a known place, but in mission terms it has barely been explored at all. A single spacecraft passed by once, more than three decades ago, and much of what we know in detail still comes from that brief encounter, combined with telescope observations since then.
Perhaps that is the perspective Neptune offers best. It reminds us that even within our own Solar System, familiarity can be an illusion. We have maps, names, orbital diagrams, and broad classifications. But some places remain mostly untrodden.
Neptune is one of them.Sources

Japan Trip Series, Part 7  Nara is just a single train ride from Dotonbori in Osaka and offers a lot in a compact area: Relatively tame deer (you’ll notice many stores use sliding doors instead of automatic ones, likely because of them), a large and walkable park, a rewarding hike with views from Mount Wakakusa, and the architectural and cultural weight of Tōdai-ji.
Nara park spans about 660 hectares and is known for its free-roaming deer and concentration of historic sites.
How does a deer sound? Watch the videos above to find out. I spent some time there, took in the atmosphere, then continued on to Mount Wakakusa.
At the top, there were wide views over Nara, open sky, and deer moving across the hillside. It was windier up there, with autumn colours starting to come through. Definitely worth it. Practical Note: Use the washroom lower down in Nara Park before starting the hike. Many public toilets in Japanese parks do not have soap, and paper towels or hand dryers are uncommon. Bring hand sanitizer, and a small hand towel if that is your preference. Back down the mountain, my route led me through the Nandaimon Gate, the main southern entrance to Tōdai-ji. Inside are the large wooden Niō guardian statues, each over 8 metres tall and carved in the 13th century. They are imposing and full of motion, even at rest.
From there, I continued into Tōdai-ji.The Daibutsuden (Great Buddha Hall) is one of the largest wooden buildings in the world and houses the Great Buddha (Daibutsu), a massive bronze Vairocana Buddha. The current structure dates to the Edo period, after earlier fires destroyed previous versions. Inside, it is the scale that stands out first, then the detail. Massive space, heavy timber, and aged surfaces, with historic statues that reward a closer look. Nara works especially well as a day trip from Osaka. A spacious park, approachable wildlife, a short but rewarding hike with wide views, an imposing gate, and a monumental temple. That is a lot of awesome in a small area. Enjoy the park. Then keep going.All photos and videos in this post were taken by me with an iPhone 17 Pro.
Japan Trip Series, Part 6 Osaka’s Dotonbori District is peak city energy. Neon lights, canal walks, constant movement, and an absurd amount of food and shopping packed into a compact area. This is part 6 of my Japan Trip Series and in this post I’ll be focusing on Dotonbori specifically. It’s a place that’s most alive after dark, efficient in the morning, and incredibly well connected for day trips.  Where I Stayed: Dotonbori Hotel (the one with the giant heads)I stayed at the Dotonbori Hotel, recognizable immediately by the giant sculpted heads out front. The location is excellent. It’s close to the canal, surrounded by shopping, and near easy transit connections. I was only there for two nights, with a day trip to Nara sandwiched in the middle, so I unfortunately did not get to take advantage of everything the hotel offers. Rooms are small but very efficient, with everything you need.
The hotel offers an impressive range of complimentary amenities. There are massage chairs in the lobby, free soft drinks and alcohol, complimentary cup noodles, and drawers of amenities and toiletries (e.g. lotion, combs, shavers, toothbrush kits, shower caps). Cultural experiences and small events are occasionally hosted in the lobby as well. I unfortunately didn’t have time to try the massage chairs or attend any of the cultural activities, but they add to the sense that the hotel is trying to provide more than just a place to sleep. I plan to make better use of these offerings the next time I stay here.  Dotonbori at Night: Neon, Crowds, and the Greatest HitsEven if you’re not aiming to do anything specific, Dotonbori becomes a destination by default. You end up walking it multiple times because it’s the connective tissue between so many places. Nighttime highlights include: The Glico Running Man. This area is packed in the evening. The neon lights and iconic 3D signs that deliver that futuristic big city feel people travel to Japan to experience. The canal and bridges, which create natural pause points where the city becomes a moving diorama. Be aware that evenings are busy. Not “avoid at all costs” busy, more like “move with the flow and don’t expect empty photos” busy. Shopping: Surprisingly Great for Figures and Nerd Finds
Food: Endless Choices, Great Prices, and Satisfying
Why Dotonbori Works as a BaseDotonbori isn’t just a fun neighbourhood. It’s strategic and practical.
In other words, Dotonbori is a stellar base. It’s a great place to sleep, a great place to explore, a great place to shop, a great place to eat, and a great place to start from when heading out for a day trip or moving on to your next major destination.  If you are planning to visit Dotonbori, here is a practical checklist
Next up in part 7: A day trip to Nara, home to ancient temples, the Great Buddha, and the famously assertive deer of Nara Park. All photos and videos in this post were taken by me with an iPhone 17 Pro.
