Many people were upset by the reclassification of Pluto as a "dwarf planet." But there was good reason for it: it turns out that there are a bunch of things in our Solar System about the size of Pluto, and Pluto isn't even the largest; Eris takes that crown, about 27% heavier than Pluto. (Although Pluto is slightly larger across)

So today, we list the members of our Solar System as being one star (the Sun), four gas giants (Jupiter, Saturn, Uranus, and Neptune), four rocky planets (Earth, Venus, Mars, and Mercury), five dwarf planets (Eris, Pluto, Haumea, Makemake, and Ceres), and about 200 known potential dwarves. (There are also 182 known moons of these various planets, of which 19 are large enough that they would count as dwarf planets if they were in orbit around the Sun. Our own is the fifth-largest)

And in fact, it looks like a new dwarf planet may have been confirmed! New measurements of one of these candidates, (225088) 2007-OR₁₀ (known as "2007OR₁₀" for short), reveal that it's actually far bigger than was previously believed, but is simply dark enough that it was previously hard to see. In fact, it's actually the third-largest of the dwarves, covered (we suspect) in a steadily-changing surface of methane ice, and 1,535km across – a surface the size of Africa.

As its rather cryptic name suggests, 2007OR₁₀ was discovered in 2007, but hasn't even been studied enough to get a formal name yet. It's likely to get one soon; by the rules of the International Astronomical Union, as a trans-Neptunian planet it should be named for a god related to creation. (See https://www.iau.org/public/themes/naming/#dwarfplanets if you're curious about the detailed rules)

What's fascinating about this is that it highlights just how hard it is to see objects in our Solar System. Planets are only visible by the light they reflect from the Sun, or by their gravitational pull on other objects. If they aren't very reflective (like Eris, whose smooth, icy surface makes it the second-shiniest object in the Solar System; only Saturn's moon Enceladus is more reflective), or massive enough to see their gravitational pull felt across the immense distances of the outer Solar System (as only the gas giants are), then they are virtually invisible. We don't actually know how many dwarf planets we have, or how large the biggest of them are, especially once you get to the far outer reaches of the system where you would only spot an item by sheer chance.

Our discovery of planets is just beginning. Even as we are finally becoming able to see things smaller than the largest gas giants in other star systems – our catalogue of known exoplanets has 3,406 entries as of today – we can't even claim a decent catalogue of the smaller planets of our own system, because they hide in its vast deeps just like unknown species hide in the depths of our oceans.

You can see some useful lists of Solar System objects at the pages below, although note that they haven't yet been updated to include the larger size of 2007OR₁₀!

In a universe full of planets, 2007 OR10 is something special. It’s big, just slightly smaller than the size of Pluto. And it’s close, within our very own solar system. So how did it still manage to take astronomers by surprise?

The problem with Oracle v. Google is that everyone actually affected by the case knows what an API is, but the whole affair is being decided by people who don’t.

Gonna start bugging the Unicode consortium to add snake segment characters that can be combined into an arbitrary-length non-breaking snake.

Nearly half of Americans would have trouble finding $400 to pay for an emergency. I’m one of them.

Annapurna is the perfect place to try South Indian style food. The dosas, idlis and vadas are as good as anything you find in South India. We had the ghee roast masala dosa and the sambar vada and that was more than enough food for the two of us. The salted Lassi is one of the best I've had in LA. The filter coffee is not that great. It's weak and seems to have instant coffee mixed with ground coffee. I'd give that a pass next time. Overall highly recommend this if you want to see another side of Indian food (aside from the chicken tikka masala - which, frankly, isn't even that good in most places here I've tried)

What can I say about In-N-Out that's hasn't been said already? I order the cheese burger and the fries. Love the milkshakes too. The potatoes are cut right there and fried fresh. Same with the burgers. Although, they don't cut their cows right there. That would have been disturbing to the common American.

Very modern coffee shop with some excellent coffee. The place is usually pretty crowded with young people working on their laptops. I like the outdoor seating with a live wall of plants. Have tried the cold nitro brew, which is a burst of caffeine minus the bitterness and has the mouth feel of a beer because of the nitrogen(?). The Gibraltar is great too.

My favourite restaurant in Torrance for food from the Indian/Pakistan subcontinent. I usually order the Lamb Pulao on Fridays. It comes with a giant hunk of tender lamb shank on a bed of fragrant rice. Two people can share easily. On other days I order the Beef Nehari with their fantastic soft Naan. For appetisers I recommend the chicken tikka BBQ kebab. My drink of choice is the Salt (savoury) Lassi. Highly recommended!

Excellent selection of beer on the tap. Lively place with an informal setup - you basically stand around wooden barrels and chat. Recommend!

Giuliano's is a magical place of real Italian food, cold cuts, cheese, and bread. What more could you ask for? Definitely have the meatball sandwich. Get there in the morning to pick up fresh bread. The pastas, pizzas, appetisers are ask excellent. Great for a hearty casual dinner, or an evening snack.

Grand Central Market is my favourite haunt in DTLA. Plenty of good food, produce, coffee and above all, if you like photographing urban spaces, and people GCM makes for beautiful photos.
